PHP : Function Reference : ODBC Functions (Unified) : odbc_connect


Connect to a datasource (PHP 4, PHP 5)
resource odbc_connect ( string dsn, string user, string password [, int cursor_type] )

Examples ( Source code ) » odbc_connect

To make a DSN-less connection using ODBC to MS-SQL:
'DRIVER={SQL Server};SERVER=<servername>;DATABASE=<databasename>';
$user 'username';
$pass 'password';
$connection odbc_connect$connection_string$user$pass );

To use MySQL via ODBC:
$db_user        "dbuser";
$db_pass        "dbpass";
$dsn "DRIVER={MySQL ODBC 3.51 Driver};" .
"CommLinks=tcpip(Host=$db_host);" .
"DatabaseName=$db_name;" .
"uid=$db_user; pwd=$db_pass";

Compiling Apache + PHP + DB2 8.1  without the DATABASE instaled at the WebServer Machine!
Go to the machine that you have DB2 DATABASE instaled and COPY the include files from the DB2 8.1 DataBase to the PHP source directory:
[root@DB2_SERVER/usr/opt/db2_08_01/include]# scp * user@webserver:/usr/src/php-4.3.7/ext/odbc/.
Enter in the WebServer as root and ...
-- DB2 --
Install Administration Client
Catalog the DataBases
-- END DB2 --
-- LIB --
vi /etc/
add line: /opt/IBM/db2/V8.1/lib
execute: ldconfig
-- END LIB --
--- APACHE ---
cd ../mod_ssl-2.8.18-1.3.31
./configure  --enable-module=so --with-apache=../apache_1.3.31 --with-ssl=../openssl-0.9.7d
cd ../apache_1.3.31/
make certificate TYPE=custom
make install
--- END APACHE ---
OBS:  CRIPT the CA.key
DO NOT CRYPT server.key
-- PHP --
cd ../php-4.3.7
./configure  --with-apxs=/usr/local/apache/bin/apxs --with-mysql --with-pgsql --with-zip=/usr/local/lib --with-ibm-db2=/opt/IBM/db2/V8.1
make install
-- END PHP ---
vim /usr/local/apache/bin/apachectl
add line: . /home/db2inst1/sqllib/db2profile
NOW run /usr/local/apache/bin/apachectl startssl
DONE !!!!!
You have a WebServer with PHP with DB2,MYSQL,POSTGRES and SSL Support.
Enjoy IT!

WINNT 4 Workstation, PHP4
odbc_connect() kept giving me weird errors when trying to connect to a MSaccess DSN(Microsoft Jet engine couldn't open the database 'Unknow'. Another user is using it exclusively, or you dont have permission to use it).
After going nuts for a while, I realized that my database name had a space in it (course surveys.mdb), I shortened the name to eliminate the space .. and everything worked fine.


While Installing PHP  + Apache + DB2 some time it give problem with odbc_connect(). . to solve this problem
make sure that u have made following entry in /etc/
please add following line on line no 25 in /etc/rc.d/init.d/httpd
(i.e /home/(instant name)/sqllib/db2profile
for more detail please visit to IBM site
it will work


We've tried hard to connect from php to our IBM DB2 RS/6000 Server. It worked after we compiled with --ibm-db2= option, but it was unbelievable
No, just testing some options, we found out that it went from very slow (getting 100 records lasts 1 till 10 seconds) to fast access (almost same speed as with using JDBC from Servlets) to 0.2 till 0.3 seconds.
We simply added the optional parameter Cursortype to odbc_connect, and with the cursortype SQL_CUR_USE_ODBC it changed in that way!
Hope this helps anybody who must connect to db2 ;)


Two additional notes regarding ODBC connections to a Network Sybase SQL Anywhere 8 Server..
I wrote a script using the PHP5 CLI binary that monitors a directory for changes, then updates a Network Server SQL Anywhere 8 database when a change was detected. Idealy, my program would run indefinately, and issue odbc_connect()/odbc_close() when appropriate. However, it seems that once connected, your odbc session is limited to 30 seconds of active time, after which, the connection becomes stale, and no further queries can be executed.  Instead, it returns a generic "Authentication violation"  error from the odbc driver.
Here's an example:
 $result=odbc_exec($qry,$conn);  //returns data
 $result=odbc_exec($qry,$conn);  //"Authentication Violation"
Additionally, it seems that odbc_close() doesn't truely close the connection (at least not using Network SQL Anywhere 8). The resource is no longer usable after the odbc_close() is issued, but as far as the server is concerned, there is still a connection present. The connection doesn't truely close until after the php script has ended, which is unfortunate, because a subsequent odbc_connect() commands appear to reuse the existing stale connection, which was supposedly closed.
My workaround was to design my script exit entirely after a the database update had completed.  I then called my script whithin a batch file and put it inside an endless loop.
I'm not sure if this is a bug with PHP or what, but I thought I'd share in case someone else is pulling their hair out trying to figure this one out...

To use MySQL via ODBC:
$db_host        = "server.mynetwork";
$db_user        = "dbuser";
$db_pass        = "dbpass";
$dsn = "DRIVER={MySQL ODBC 3.51 Driver};" .
"CommLinks=tcpip(Host=$db_host);" .
"DatabaseName=$db_name;" .
"uid=$db_user; pwd=$db_pass";
odbc_connect($dsn, $db_user, $db_pass);


To make a DSN-less connection using ODBC to MS-SQL:
$connection_string = 'DRIVER={SQL Server};SERVER=<servername>;DATABASE=<databasename>';
$user = 'username';
$pass = 'password';
$connection = odbc_connect( $connection_string, $user, $pass );
servername is the name of the database server
databasename is the name of the database
Note, I've only tried this from a windows box using the Microsoft ODBC drivers.


To connect to Sybase SQL Server Anywhere 8.0 on Windows use the following:
 // Configure connection parameters
 $db_host        = "server.mynetwork";
 $db_server_name = "Dev_Server";
 $db_name        = "Dev_Data";
 $db_file        = 'c:\dbstorage\dev.db';
 $db_conn_name   = "php_script";
 $db_user        = "dbuser";
 $db_pass        = "dbpass";
 $connect_string = "Driver={Adaptive Server Anywhere 8.0};".
 // Connect to DB
 $conn = odbc_connect($connect_string,'','');
 // Query
 $qry = "SELECT * FROM my_table";
 // Get Result
 $result = odbc_exec($conn,$qry);
 // Get Data From Result
 while ($data[] = odbc_fetch_array($result));
 // Free Result
 // Close Connection
 // Show data


To connect to a SQL DB on a unix srv via odbc one can use one of the following solutions.
1. having an odbc.ini (~/.odbc.ini)
Description         = PostgreSQL template1
Driver              = PostgreSQL
Trace               = Yes
TraceFile           = /tmp/odbc.log
Database            = PerfTest
Servername          = localhost
UserName            = boss
Password            = BigBoss
Port                = 5432
Protocol            = 6.4
ReadOnly            = Yes
ConnSettings        =
Driver = /local/lib/
2. specifying a DSN
function DBCALL($SQL)
$U = "boss";
$DB = "PerfTest";
$P = "BigBoss";
$Srv = "llocalhost";
$DSN = "Driver=PostgreSQL;Server=$Srv;Database=$DB";

echo "Trying to connect to $DSN\n";
if ($CID = odbc_connect ("$DSN","$U","$P",SQL_CUR_USE_ODBC))
echo "still trying CID = $CID\n";
if ($RES = odbc_exec($CID, $SQL))
echo "RES = $RES\n";
echo "\n";

$NR = odbc_num_rows($RES);
Hope this helps.


To connect to a PROGRESS database using ODBC you must have SQL_CUR_USE_ODBC  as the 4th parameter eg odbc_connect(DSN,uname,password,SQL_CUR_USE_ODBC ) otherwise you can pass queries but no results are ever returned .


To connect to a MDB Access file without adding a system dsn to Windows :
$cfg_dsn = "DRIVER=Microsoft Access Driver (*.mdb);
$cfg_dsn_login = "";
$cfg_dsn_mdp = "";

ray.paseur sometimes uses gmail

To connect and show tables in a Microsoft Access data base (created in *.asp pages)...
$dbq = str_replace("/", "\\", $_SERVER["DOCUMENT_ROOT"]) . "\\path\\to\\database.mdb";
if (!file_exists($dbq)) { echo "Crap!<br />No such file as $dbq"; }
$db_connection = odbc_connect("DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=$dbq", "ADODB.Connection", "password", "SQL_CUR_USE_ODBC");
$result = odbc_tables($db_connection);
while (odbc_fetch_row($result)) {
if(odbc_result($result,"TABLE_TYPE")=="TABLE") {
echo "<br />" . odbc_result($result,"TABLE_NAME");


Thought I'd add a note here on this. I'm using Apache 2.0.39 on Windows XP and PHP 4.2.2.
It helps a lot if you don't use capital letters in your dsn string.
Thought I also comment on the posts about using system dsns over file dsns. There are lots of posts saying use systems not files, but none (that I have seen) which explain why.
Essentially: File DSNs are specific to the current user, therefore the Internet Guest User Account doesn't have rights to them. Systems are available to everyone.

This is the typical solution with the steps to follow if someone wants to connect MS Access to PHP. it took me a couple of hours actually till i reached it. i just wanted to ease the hassle for my colleagues in order not to waste their time as i did. this is the duty of every programmer towards his/her peers :p
here you are the CAKE :)
// to have this working:
// 1- u  have first to creat ur access database using MS
//     Access  (i asume u know how to do this). My database
//     that i used in my example is called "Questionaire.mdb".
//     the table in it is called "Results"
// 2- then u have to add this database to ODBC in the
//     control panel.
// 3- the adition happens by adding "MS Access Driver" to the
//     "System DNS" tab in ODBC Data Source Administrator. if
//     u have that "MS Access Driver" in "User DNS" tab, then
//     u have to delete it.
// 4- click on Add in the "System DNS" tab.
// 5- choose "MS Access Driver" from the "Creat New
//     Database Source" window and click finish.
// 6- then the "ODBC MS Access Setup" window will pop-up.
// 7- give the driver the name that you want to use in your
//     PHP scripting. i used here "MSAccessDriver".
// 8- after this, choose the "Select" button in "ODBC MS
//     Access Setup" to set the path of your Access database.
// 9-then u r done!!
// this odbc_connect does the connection to the driver i
// created in the ODBC Administrator
$con = odbc_connect('MSAccessDriver','','');  
if ($con)
 echo "odbc connected
 $sql =  "select * from Results";
 //this function will execute the sql satametn in  
 //correspondance to the table in the db
 $exc = odbc_exec($con,$sql);  
 echo "odbc not connected

 echo "selection completed
 while($row = odbc_fetch_row($exc) )
      echo $row->id."
 echo "selection failed

odbc connect to Oracle / NT4 / IIS4 / php.exe (4.1.0)
had a lot of trouble connecting kept receiving the 12154 TNS error.  
Found a really useful hint in a mail msg on phpbuilder.
Had to strip the <cr>'s out of both sqlnet.ora and tnsnames.ora to get a connection established.  Also had trouble in php.ini need to
fully qualify extension_dir on NT if you leave the last \ on the dir
name it is replaced with a /


If you're connecting to a SQL server database through ODBC, you must set the default database of the ODBC DSN to the database you want to use.
There is no way to specify the database name in odbc_connect or odbc_pconnect, just the DSN name, username, and password.


If you have switched to a new Version of PHP (from 4.1 to 4.3) and at the same time have upgraded your Apache server (from 1.x to 2.x) and suddenly get the error:
"[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified, SQL state IM002 in SQLConnect"
It may be because you have your ODBC connections listed (Control Panel | ODBC) as User DSN rather than System DSN.  They need to be System DSN in order for the PHP in the Apache service to access to them.


If you have problem to connect to sybase with an ODBC driver, try to set up your SYBASE environment variable to the correct directory.
([ODBC SQL Server driver]Allocation of a Sybase Open Client Context failed)
Ex : Here is a connection to a DSN
$conn  =  odbc_connect("DSN1","USER","PASSWORD");
echo  "conn:  $conn";
if  ($conn  <=  0)  {
       echo  "Error  in  connection";
} else  {
       echo  "

Connection  successful\n";


If you encounter the error:
"[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified, SQL state IM002 in SQLConnect"
Windows with PHP, running under IIS/PWS, PHP runs under the anonymous user, INET_USR_"server" (were "server" is your servername).
This user has no read access in the ODBC System DSN tree in the registry.
With regedt32 open HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBC_INI and give read access to every ODBC entry you want to use with PHP.
Beware: With every change to a ODBC system DSN, the rights on that ODBC system DSN are gone again, and you have to change the rights again manualy.
Under Apache, PHP runs under the System account and you wont have this problem.


If you encounter the error:
"[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified, SQL state IM002 in SQLConnect"
make sure you have the correct permission to your database file (e.g. if using Win2k, might want to set the "Everyone" group to "Full Control").  For Windows, I find that I have to sometimes use the registry editor (e.g. RegEdt32.exe) to set the database file's permission because for some unknown reason, setting the permission from the file's "Properties" option does not work.


If you don't want to specify your login credentials on your web server, you can leave the login fields blank to use the integrated windows security like here:
Make sure you have switched your system dsn to integrated security, too !
(works on windows machines only, of course)


If you (still) get that annoying error like and you're using Access:
MSaccess DSN(Microsoft Jet engine couldn't open the database 'Unknow'.
Another user is using it exclusively, or you dont have permission to use
Make sure your access *.mdb file is not on a network drive. Put it on C: or D: disable all security first so you can test the connection. Once you can verify that you can connect add appropriate passwords, group access, etc.

If using Openlink to connect to a Microsoft Access database, you will most likely fine tha odbd_connect() works fine, but discover that ANY query will produce odd results; with SELECT queries failing with "[OpenLink][ODBC][Driver]Driver not capable, SQL state
S1C00 in SQLExecDirect in xxxx.php on line xx" and INSERT / DELETE queries warning "No tuples available at this result index".
In this case, use the SQL_CUR_USE_ODBC cursor!
This had me stumped for quite some time; because it was the odbc_exec() which was seemingly at fault... :)


If like me you are using openlink from unix to access an MS Access database on an NT/Win2k machine and find out that your INSERT queries don't do anything and don't report any errors, use odbc_pconnect().
I couldn't understand what was going on and after a bit of research I found out that with MySQL they recommended using mysql_pconnect() for INSERT queries. I tried the same thing with odbc and it worked.


i'm using Apache/1.3.12 (Win32) with php4 module to get data from sql server7.0 via odbc.. and it's works ! Thanks very much.. Hope this script help the others as i were helped =)
define (NL,"\n");
$cur=odbc_exec($cx,"select id,nama from php");
echo "<table border=1 align=center>".NL;
echo "<tr><td>ID</td>".NL."<td>Pass</td></tr>";
echo "<tr>".NL;
echo "<td>".NL;
echo "$id".NL;
echo "</td>".NL;
echo "<td>".NL;
echo "$pass".NL;
echo "</td>".NL;
echo "</tr>".NL;
echo "</td>".NL;
echo "</table>".NL;

I fighted with the "Data source name not found and no
default driver specified, SQL state IM002 in SQLConnect"
error for a while trying to connect via ODBC to a SQL Server
2000. Finally I found this workaround:
$cn = odbc_connect("Driver={SQL Server};Server=MyServer;Database=MyDatabase",
Change "MyServer", "MyDatabase", "MyUser" and "MyPassword" to the right values.
I guess that adding the "Integrated Security=YES" will work too.

I also had a problem with this message: ([ODBC SQL Server driver]Allocation of a Sybase Open Client Context failed). The message only appeared after the server had run for a few hours, so I expected resource starvation. However it was a settings problem and I thought this might benefit others too.
In addition to putting a <?php putenv ("SYBASE=c:\sybase"); ?>  as described by oottavi above, I also had so specify a locale by setting <?php putenv ("LC_ALL=default"); ?>.
Even though my locale was already set to a valid one (en_US) I had to set this environment variable to make it work anyhow.

here's a quick note about using php and db2 that cost me a couple of hours and several recompiles trying to figure out why it didn't work.
put the below line in any script
Or, set that in your webserver environment somehow.

For three days I fought to be able to connect our Linux intranet server to our AS400 database through ODBC and PHP on Mandrake. I installed everything I thought would work but I still got a: odbc_connect(): SQL error: Missing server name, port, or database name in call to CC_connect., SQL state IM002 in SQLConnect
Note that isql was working great but php was failing to connect.
The solution:
I located and found a PHP module called php-unixODBC (to oppose with php-odbc). Once installed (even though it wasn't for the right version of PHP), I realised it didn't place the file properly. The ini file was in /etc/php/ instead of /etc/php.d/, so I moved it there and renamed the old /etc/php.d/36_odbc.ini to /etc/php.d/36_odbc.ini.sav, so that I now had /etc/php.d/36_unixodbc.ini. I restarted the httpd server and now I was able to access the as400.

For connection to Informix database via ODBC, there are some problem (depending from the version of DB).
It's possible, if you have ver. 2.x or 3.x, than in insert query mode a double string, the server answer :
[Informix][Informix ODBC Driver][Informix]Character to numeric conversion error, SQL state 37000 in SQLExecDirect in server/page.php.
The only way to resolve the problem to resolve the problem is add the US-English locales to the PHP connection.


For anyone having problems with WHERE clauses in their MS Access ODBC requests here’s what I found: SQL requests sent to Access must include quotes around the criteria.
$sel = "SELECT * FROM table1 WHERE cust_id = 'cust1'";
SELECT * FROM table1 WHERE cust_id = 'cust1'
And works.
$sel = ‘SELECT * FROM table1 WHERE cust_id = cust1’;
SELECT * FROM table1 WHERE cust_id = cust1
And doesn’t work.
Here’s the whole block of code:
$conn = odbc_connect("database1","","");
$sel = "SELECT * FROM table1 WHERE cust_id = 'cust1'";
$exec = odbc_exec($conn,$sel);
while($row = (odbc_fetch_array($exec)))
$serv[odbc_result($exec,'label')] = $row;


Due to multiple requests, more for DSN-less connections:
$db_connection = new COM("ADODB.Connection");
$db_connstr = "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=". realpath("../databases/database.mdb") ." ;DefaultDir=". realpath("../databases");
$rs = $db_connection->execute("SELECT * FROM Table");
$rs_fld0 = $rs->Fields(0);
$rs_fld1 = $rs->Fields(1);
while (!$rs->EOF) {
 print "$rs_fld0->value $rs_fld1->value\n";
 $rs->MoveNext(); /* updates fields! */
(Prints first 2 columns for each row.)

Connecting with SQL in a ODBC source
2 ways, one is if your SQL server is runign in your machine
$ser="LOCALMACHINE"; #the name of the SQL Server
$db="mydatabase"; #the name of the database
$user="myusername"; #a valid username
$pass="my pass"; #a password for the username
# one line
$conn=odbc_connect("Driver={SQL Server};Server=".$ser.";Database=".$db,$user,$pass);
# one line
the second way is if the SQL Server is runing in other machine but in the same network
$ser="LOCALMACHINE"; #the name of the SQL Server
$db="mydatabase"; #the name of the database
$user="myusername"; #a valid username
$pass="my pass"; #a password for the username
#one line
$conn=odbc_connect("DRIVER=SQL Server;SERVER=".$ser.";UID=".$user.";PWD=".$pass.";
#one line


Connecting to an access database was as simple as the following line for me.
odbc_connect("DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=" . str_replace("/", "\\", $_SERVER["DOCUMENT_ROOT"]) . "\_database\dbname.mdb", "", "")


Connecting to ADS (Advantage Database Server) using Windows. When you setup data source in ODBC Manager (PHP_SERVER) don't use a mapped drive in Database or Data Dictionary Path, or you cannot connect:
Lets suppose that you share C:\ADS_SERVER\ADS as ADS.
Mapping to a drive X: in PHP_SERVER
Instead of:
use UNC:
if the ADS ODBC dialog don´t let you to browse a Network Drive type it manually


Connect to an MS-Access Database on the Network via ODBC
Apache 2.0.47 with PHP 4.3.4 running on Windows XP Pro
If you encounter the error
"[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified, SQL state IM002 in SQLConnect"
you should make sure to have the following done:
The ODBC-link must be a System-DNS and not a User-DNS. Configure your ODBC-link and then modify your configuration with regedt32. Go to HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBC_INI and open your ODBC-link. The field DBQ contains the path to your database. This path must be without Drive-names (e. g. "M:") so change it to "\\Server\folder\database.mdb". This setting is changed each time you modify your ODBC-configuration using the Windows-tool, so make sure you do this afterwards.
Then you go to the Services-Section in your Systemmanagement. Select the properties of your Apache module. In the login-section you have to make sure you login with a valid User-Account for your Network-Server.
Please note that this way you still have no permission to access linked tables within the linked database
Funny enough all this is not necessary on Win98.


Concerning the note posted by Grisu on the 23-Dec-2003 11:51: Connect to an MS-Access Database on the Network via ODBC,
PLEASE dont forget to put double slashes as follows:
when setting up the registry key as indicated...


Because the dsn needs to be system-wide, you will also need write access to the registry to set it up.


As always Microsoft is clueless... I've been trying to connect to an Access database on a W2K on the network (not a local file, but mapped on the V: drive), via ODBC.
All I got is this message:
Warning: SQL error: [Microsoft][ODBC Microsoft Access Driver] '(unknown)' is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides., SQL state S1009 in SQLConnect in d:\apache\cm\creaart.php on line 13
So... I started looking al around and looks like the ODBC driver has some severe problems:
1. It cannot access a Access database via a mapped drive. And this is for ANY application, name it PHP, Coldfusion, whatever
2. You cannot make a system DSN with a UNC (\\Server\resource), so you must map the drive
Cute isn't it?
So... I quit on ODBC and went via ADO, this is the code that works:
=== CODE ===
$db = '\\\\server\\resource\\db.mdb';
$conn = new COM('ADODB.Connection');
$conn->Open("DRIVER={Driver do Microsoft Access (*.mdb)}; DBQ=$db");
// Driver do Microsoft Access (*.mdb)
// must be the name in your odbc drivers, the one you get
// from the Data Sources (ODBC).
// In this case, I'm in Mexico but the driver name is in portuguese, thanks Microsoft.
$sql = 'SELECT username FROM tblUsuarios';
$res = $conn->Execute($sql);
while (!$res->EOF)
print $res->Fields['username']->Value . "
$res = null;
$conn = null;
=== /CODE ===


As a follow up to my previous post regarding "PHP get data from IBM Tivoli Netcool ObjectServer (Sybase database)", the link to the article has changed and is now:


Alot of people share the same kind of problems getting this setup on linux.  I was assigned this problem 2 days ago and I was successful.  My combination was PHP4 RC2, Easysoft OOB, and unixODBC.  These three products work very well together and are real easy to install.  More info ps also works good with Perl's DBI.


After much testing, and I think supported by a comment I found in the code, I have come to a disturbing conclusion: odbc_connect() in PHP4.04pl1 is really an odbc_pconnect(), with all the implications for transaction scoping.  Specifically, each time you call odbc_connect( "X", "" "" ), you will get the same physical ODBC Connection, and odbc_commit() and odbc_rollback() will affect all copies.  The only solution I could find was to use several different DSNs to access the database.


After doing "harald dot angel at gmail dot com" suggestion, you may still receive this error:
"Warning: odbc_connect() [function.odbc-connect]: SQL error: [Microsoft][ODBC Microsoft Access Driver] The Microsoft Jet database engine cannot open the file '(unknown)'. It is already opened exclusively by another user, or you need permission to view its data., SQL state S1000 in SQLConnect in... "
You may need to include the <computer name> of the machine where the ODBC is, to the <local group> of the machine where the *.mdb is stored. And make sure that the <local group> has enough permission to access the *.mdb.
hope this make somebody more happy!
more power to opensource.

If like me you are developing on a stand-alone system (Windows XP professional running IIS).  Make sure that the the folder your database resides in is shared, otherwise you will get the following type of message:
Current Recordset does not support updating. This may be a limitation of the provider, or of the selected locktype.'
and you will spend 2 days (as I did) looking for the right combination of settings to write the record properly.

- Windows - OS
- Apache
- ODBC-Connction to MS-Access DB on a:
- Network Share
After many hours searching here´s how it works:
- Map the Network Drive where the mdb is located
- Setup System DSN in Control Panel with mapped Drive
- Open Registry at:
- Edit the for example "M:\" to "\\server\..."
- Close Regedit
- The Apache-Service must run with a Domain (network)-User!!
- After that you can connect using:
$conn = odbc_connect('your-dsn-name','','');
hope that makes someone happy :)
