PHP : Function Reference : Filesystem Functions : file_exists

file_exists

Checks whether a file or directory exists (PHP 4, PHP 5)
bool file_exists ( string filename )

Checks whether a file or directory exists.

Parameters

filename

Path to the file or directory.

On windows, use //computername/share/filename or \\computername\share\filename to check files on network shares.

Return Values

Returns TRUE if the file or directory specified by filename exists; FALSE otherwise.

Warning:

This function returns FALSE for files inaccessible due to safe mode restrictions. However these files still can be included if they are located in safe_mode_include_dir.

Note:

The check is done using the real UID/GID instead of the effective one.

Examples

Example629.Testing whether a file exists

<?php
$filename
= '/path/to/foo.txt';

if (
file_exists($filename)) {
echo
"The file $filename exists";
} else {
echo
"The file $filename does not exist";
}
?>


Notes

Note:

The results of this function are cached. See clearstatcache() for more details.

Tip:

As of PHP 5.0.0 this function can also be used with some URL wrappers. Refer to AppendixO, List of Supported Protocols/Wrappers for a listing of which wrappers support stat() family of functionality.

This solution works for me. Just need to fix a typo in the original post:
$fileUrl = "http://www.examplecom/test.jpg";
$AgetHeaders = @get_headers($fileUrl);
if (preg_match("|200|", $AgetHeaders[0])) {
// file exists
} else {
// file doesn't exists
}

This is an example if you want to know that a file exists (if that file isn't on your server):
$fileUrl = "http://www.examplecom/test.jpg";
$AgetHeaders = @get_headers($sourcePath);
if (preg_match("|200|", $AgetHeaders[0])) {
// file exists
} else {
// file doesn't exists
}

feshi

this code looks inocent
<?php
$filename=$_REQUEST["var"];
$filename .= ".data";
file_exist($filename){
 include($filename);
}
?>
but if you pass something like script.php?var=test%00asbs
it should really can do bad things like including accesslog files if you replace "test" with something like "../logs/accesslog"


ihoss dot com

The following script checks if there is a file with the same name and adds _n to the end of the file name, where n increases. if img.jpg is on the server, it tries with img_0.jpg, checks if it is on the server and tries with img_1.jpg.
<?php
 $img = "images/".$_FILES['bilde']['name'];
 $t=0;
 while(file_exists($img)){
   $img = "images/".$_FILES['bilde']['name'];
   $img=substr($img,0,strpos($img,"."))."_$t".strstr($img,".");
   $t++;
 }
 move_uploaded_file($_FILES['bilde']['tmp_name'], $img);
?>

The following code will rename an uploaded image to a MD5 hash with a rand number added of its name and check wheter a file with same hash already exists or not:
<?php
$file = $HTTP_POST_FILES['file'];
$image=new Image($imgfld,$file);
if($image->FType != null){
if ($image->FType=="image/gif") {
$ext = ".gif";
}else{
$ext = ".jpg";
}
$nfile = md5($image->Name . rand());
while(file_exists($imgfld . $nfile . $ext) == true){
$nfile = md5($image->Name . rand());
}
$image->ResizedWidth = $imggrx;
$image->ResizedHeight = $imggry;
$image->Resample($nfile);
?>
It uses an image class found at phpclasses.org

That is true feshi. But, if you have your server configured correctly, those access logs will only be accessible by an admin or the root account. The webuser account that runs the php script will be unable to start reading from that file. That's the easiest fix.

Small error in florinel2k's example
$sourcePath should be $fileUrl, otherwise it works well for me.
//Corrected
This is an example if you want to know that a file exists (if that file isn't on your server):
$fileUrl = "http://www.examplecom/test.jpg";
$AgetHeaders = @get_headers($fileUrl);
if (preg_match("|200|", $AgetHeaders[0])) {
// file exists
} else {
// file doesn't exists
}

On nix systems file_exists will report a link that doesn't point to a valid file as non-existant, ie: the link itself exists but the file it points to does not.  Using is_link will report true whether the link points to a valid file or not.

seejohnrun

not to overshadow anyone making url_exists functions, but...
function url_exists($url) {
    if ((strpos($url, "http")) === false) $url = "http://" . $url;
    if (is_array(@get_headers($url)))
         return true;
    else
         return false;
}
enjoy!

Nathaniel, you should read the manual carefuly next time prior to posting anything here, as all you indicated is the fact you missed the idea of the include_path. To remind - include_path is for some functions only, mainly intended for include and require to simpify include/require operations (kinda way the #include works). It is NOT for any filesystem function, which would be damn annoying than helpful, which is quite understandable and obvious.

vernon

In response to seejohnrun's version to check if a URL exists. Even if the file doesn't exist you're still going to get 404 headers.  You can still use get_headers if you don't have the option of using CURL..
$file = 'http://www.domain.com/somefile.jpg';
$file_headers = @get_headers($file);
if($file_headers[0] == 'HTTP/1.1 404 Not Found') {
   $exists = false;
}
else {
   $exists = true;
}

In response to havran at gmail dot com
Your function url_exists() does not work because it has got a big bug. curl_init does not make a connection to that url until curl_exec() is executed. The return value from curl_init() shows if a curl session can be started.
That function can be rewritten as follows
<?php
class Url
{
/**
* Check if an url is existed
*
* @param  string    $url
* @access static
* @return bool      True if the url is accessible and false if the url is unaccessible or does not exist
* @throws Exception An exception will be thrown when Curl session fails to start
*/
public static function exists($url)
{
if (null === $url || '' === trim($url))
{
throw new Exception('The url to check must be a not empty string');
}

$handle   = curl_init($url);
if (false === $handle)
{
throw new Exception('Fail to start Curl session');
}
curl_setopt($handle, CURLOPT_HEADER, false);
curl_setopt($handle, CURLOPT_NOBODY, true);
curl_setopt($handle, CURLOPT_RETURNTRANSFER, false);
// grab Url
$connectable = curl_exec($handle);
// close Curl resource, and free up system resources
curl_close($handle);
return $connectable;
}
}
?>
How to use:
<?php
try
{
   if (Url::exists('http://phpvietnam.net'))
   {
       // Do something here    
   }
}
catch (Exception $ex)
{
   // Do something here
}
?>


adam

In regards to the function url_exists below... the reason it's slow is because of fopen().  
I tried this function with a loop of 25 urls, and output the time spent using microtime(), which ended up taking 4.6 seconds.
I wrote a new function using fsockopen() and tried with the same 25 urls.  Time spent, 1.1 seconds.  More than 4 times as fast.  
Another issue with it, I don't know if this is a problem or not, but fopen() returns true if the url results in a 500 Internal Server Error.  fsockopen() returns false in this case.
I don't know if this is the fastest/most efficient method, but I think it's a nice alternative regardless.  Here's the function:
<?php
function url_exists($url){
if(strstr($url, "http://")) $url = str_replace("http://", "", $url);
$fp = @fsockopen($url, 80);
if($fp === false) return false;
return true;
}
?>


aidan

If you'd like to check if a file exists anywhere your include path, have a look at this function:
http://aidanlister.com/repos/v/function.file_exists_incpath.php


alex

If you use open_basedir in php.ini and use file_exists for file outside open_basedir path, you will not be warned at log and file_exists returns false even if file really exists.

bvazquez

If you are trying to access a Windows Network Share you have to configure your WebServer with enough permissions for example:
$file = fopen("\\siscomx17\c\websapp.log",'r');
You will get an error telling you that the pathname doesnt exist this will be because Apache or IIS run as LocalSystem so you will have to enter to Services and configure Apache on "Open a session as" Create a new user that has enough permissions and also be sure that target share has the proper permissions.
Hope this save some hours of research to anyone.


earle dot west

If the file being tested by file_exists() is a file on a symbolically-linked directory structure, the results depend on the permissions of the directory tree node underneath the linked tree.   PHP under a web server (i.e. apache) will respect permissions of the file system underneath the symbolic link, contrasting with PHP as a shell script which respects permissions of the directories that are linked (i.e. on top, and visible).  
This results in files that appear to NOT exist on a symbolic link, even though they are very much in existance and indeed are readable by the web server.


tma

If checking for a file newly created by an external program in Windows then file_exists() does not recognize it immediately.  Iy seems that a short timeout may be required.
<?
   $file = 'file.tmp';
   if ($h = popen("start \"bla\" touch $file", "r")) {
     pclose($h);
  // now I would like know if a file was created
  // note: usleep not supported
     $start = gettimeofday();  
     while (!file_exists(trim($file, " '\""))) {
       $stop = gettimeofday();
       if ( 1000000 * ($stop['sec'] - $start['sec']) + $stop['usec'] - $start['usec'] > 500000) break;  // wait a moment
    }
    if (file_exists($file))   // now should be reliable
?>

I wrote this little handy function to check if an image exists in a directory, and if so, return a filename which doesnt exists e.g. if you try 'flower.jpg' and it exists, then it tries 'flower[1].jpg' and if that one exists it tries 'flower[2].jpg' and so on. It works fine at my place. Ofcourse you can use it also for other filetypes than images.
<?php
function imageExists($image,$dir) {
   $i=1; $probeer=$image;
   while(file_exists($dir.$probeer)) {
       $punt=strrpos($image,".");
       if(substr($image,($punt-3),1)!==("[") && substr($image,($punt-1),1)!==("]")) {
           $probeer=substr($image,0,$punt)."[".$i."]".
           substr($image,($punt),strlen($image)-$punt);
       } else {
           $probeer=substr($image,0,($punt-3))."[".$i."]".
           substr($image,($punt),strlen($image)-$punt);
       }
       $i++;
   }
   return $probeer;
}
?>

I wrote a very simple function that allows you to search a folder for a file name with a regular expression. It can handle both PREG and EREG regexps and can accept different case sensitivities for EREG regexps.
function regExpFile($regExp, $dir, $regType='P', $case='') {
# Two parameters accepted by $regType are E for ereg* functions
# and P for preg* functions
$func = ( $regType == 'P' ) ? 'preg_match' : 'ereg' . $case;
# Note, technically anything other than P will use ereg* functions;
# however, you can specify whether to use ereg or eregi by
# declaring $case as "i" to use eregi rather than ereg
$open = opendir($dir);
while( ($file = readdir($open)) !== false ) {
if ( $func($regExp, $file) ) {
return true;
}
} // End while
return false;
} // End function
Basically if you supply anything but "P" for $regType it will assume you're using EREG regexps. The case should only be blank or "i".


guillermogomezruiz

I was having problems with the file_exists when using urls, so I made this function:
<?php
function file_exists_2($filePath)
{
return ($ch = curl_init($filePath)) ? @curl_close($ch) || true : false;
}
?>
Cheers!


nathaniel

I spent the last two hours wondering what was wrong with my if statement: file_exists($file) was returning false, however I could call include($file) with no problem.
It turns out that I didn't realize that the php include_path value I had set in the .htaccess file didn't carry over to file_exists, is_file, etc.
Thus:
<?PHP
// .htaccess php_value include_path '/home/user/public_html/';
// includes lies in /home/user/public_html/includes/
//doesn't work, file_exists returns false
if ( file_exists('includes/config.php') )
{
    include('includes/config.php');
}
//does work, file_exists returns true
if ( file_exists('/home/user/public_html/includes/config.php') )
{
   include('includes/config.php');
}
?>
Just goes to show that "shortcuts for simplicity" like setting the include_path in .htaccess can just cause more grief in the long run.

I recently had an issue with PLESK and copying file to other directories with the move_uploaded file function.
This would work on every linux server except plesk servers. I could figure it out and have yet to find out.  I had to create a work a round and decided to use the exec() function.
As noted above the file_exist() function must need to wait for some time and I found the looking function a waste of resouces and didn't work for me anyway. So this is what I came up with.
function cp($source,$destination){
$cmd="cp -u ".$source ." ".$destination; //create the command string to copy with the update option
exec($cmd); //exec command
$cmd_test="ls -la ".$destination; //list file
exec($cmd_test,$out);
//If the file is present it $out[0] key will contain the file info.
//if it is not present it will be null
if (isset($out[0])){
    return true;
}else{
    return false;
}
}

here a function to check if a certain URL exist:
<?php
function url_exists($url) {
$a_url = parse_url($url);
if (!isset($a_url['port'])) $a_url['port'] = 80;
$errno = 0;
$errstr = '';
$timeout = 30;
if(isset($a_url['host']) && $a_url['host']!=gethostbyname($a_url['host'])){
$fid = fsockopen($a_url['host'], $a_url['port'], $errno, $errstr, $timeout);
if (!$fid) return false;
$page = isset($a_url['path'])  ?$a_url['path']:'';
$page .= isset($a_url['query'])?'?'.$a_url['query']:'';
fputs($fid, 'HEAD '.$page.' HTTP/1.0'."\r\n".'Host: '.$a_url['host']."\r\n\r\n");
$head = fread($fid, 4096);
fclose($fid);
return preg_match('#^HTTP/.*\s+[200|302]+\s#i', $head);
} else {
return false;
}
}

in my CMS, I am using it with those lines:
<?php

$this->f_exist[$image]['exist'] = $this->url_exists($fimage); //for now
} else {
$this->f_exist[$image]['exist'] = ($fimage!='' && file_exists($fimage) && is_file($fimage) && is_readable($fimage) && filesize($fimage)>0);

Full-featured function to check if a file exists on an external server
Using snippets of code from below and some of my own I knocked this up because I wanted to check a URL from user input, and to be able to tell exactly what is wrong with a URL, not simply if it's true or false.  This function also bypasses any need for the server to check for URLs that simply aren't going to exist
I got the big list of domain tlds from http://data.iana.org/TLD/tlds-alpha-by-domain.txt
<?php
### check file exists on external server - returns numeric values for false, a full URL string for true.
// ext = optional file extension, like html, mp3, jpg... stops checking if doesn't meet this condition

For some reason, none of the url_exists() functions posted here worked for me, so here is my own tweaked version of it.
<?php
   function url_exists($url){
       $url = str_replace("http://", "", $url);
       if (strstr($url, "/")) {
           $url = explode("/", $url, 2);
           $url[1] = "/".$url[1];
       } else {
           $url = array($url, "/");
       }
       $fh = fsockopen($url[0], 80);
       if ($fh) {
           fputs($fh,"GET ".$url[1]." HTTP/1.1\nHost:".$url[0]."\n\n");
           if (fread($fh, 22) == "HTTP/1.1 404 Not Found") { return FALSE; }
           else { return TRUE;    }
       } else { return FALSE;}
   }
?>


andrewnospamplease

file_exists will have trouble finding your file if the file permissions are not read enabled for 'other' when not owned by your php user. I thought I was having trouble with a directory name having a space in it (/users/andrew/Pictures/iPhoto Library/AlbumData.xml) but the reality was that there weren't read permissions on Pictures, iPhoto Library or AlbumData.xml. Once I fixed that, file_exists worked.

flobee

file_exists overwrites the last access (atime) !
try:
if (@fclose(@fopen( $file, "r"))) {
                // true;
            } else {
                // false;
            }
to check if important for you


stefan

file_exists and safe_mode
file_exists under safe_mode works (I work with for php 4) doesn't work when owner of the dir where the file stands differs from the php-owner.
e.g. file_exists in this dir will give FALSE nevertheless the file exists
rights           owner   dir
drwxr-xr-x    apache  images
change the owner of the dir to the phpowner and file_exists works.
I spent too much time to discover. Hope it will spare a lot of your time.

stephen dot reay

developing a CMS, with a link checker, it caused issues that when running on Win32, file_exists shows no error for case differences between the file on disk and the file you query for. this causes an issue when putting content created on the Win32 box onto a *NIX box.
the following is a function to test for files with case sensitivity, regardless of the OS. it returns 1 for a match, 0 for fails, and 2 if the file exists but with a different case.
function file_exists_case($strUrl)
{
$realPath = str_replace('\\','/',realpath($strUrl));

if(file_exists($strUrl) && $realPath == $strUrl)
{
return 1; //File exists, with correct case
}
elseif(file_exists($realPath))
{
return 2; //File exists, but wrong case
}
else
{
return 0; //File does not exist
}
}


joe dot knall

concerning file_exists and safe_mode:
if safe_mode=ON and $file (in safe_mode_include_dir) is not owned by the user who executes file_exists($file), file_exists returns FALSE but still $file can be included;
I could handle this by setting safe_mode_gid=On and appropriate group-ownership


hiro

As of php 5.0.4, many (if not all) php file manipulation functions fail if a file's size is no smaller than 2GB (i.e. 2^31) on the x86 platforms. Even file_exists() fails (always returns FALSE). This puzzled me when I was writing a video file manipulation application.
A simple alternative is like:
function file_exists_2gb($filename) {
   system("test -f $filename", $rval);
   return ($rval == 0);
}


davidc

Also while using the file_exists file, please make sure you do not start using stuff like,
<?php
if(file_exists($_GET['file'] . '.php')) {
   include($_GET['file'] . '.php';
}
?>
you could use something like this..
<?php
   $inrep = "./";
   $extfichier = ".php";
   $page = $inrep.basename(strval($_REQUEST["page"]),$extfichier).extfichier;
   if(file_exist($page)) {
       include($page);
   }
?>
or even hardcode it.
 So since pretty much all commercial server(s) have url_fopen on.. you can imagine that file_exists($_GET['file']. '.php')
is rather .. unsecure :)

function sys_file_exists($f = NULL)
{
 $h = array();
 $ret = FALSE;
 if(!is_null($f)):
   if(preg_match('/^http|https|ftp/',$f)): //test protocol EXTERN
     $h = @get_headers($f);
     if(array_key_exists(0,$h)) :
       $ret = (bool) preg_match('/200|301/',$h[0]); /* HTTP/1.1 301 DAP (directory) */
     endif;
   else: //else FS
     $ret = (file_exists($f) && is_readable($f));
   endif;
 endif;
 
 return (($ret === TRUE) ? TRUE : FALSE);
}
then, it's easy to replace file_exists in your code,
grep -R file_exists path/to/frameworks
...
private function _loadModel($file = NULL)
{
 //TRACE($file);
 
 try {
   if(is_null($file) || !sys_file_exists($file)) :
     throw new SF_websiteview_exception('loadModel : '.$file.' could not be loaded');
   endif;
 } catch(SF_websiteview_exception $ex){$ex->trace(FALSE);}
 
 return file_get_contents($file);
}
...
private function _loadtable($file)
{
 try {
   if(sys_file_exists($file)):
     $buf = file($file);
   else:
     throw new SF_localization_exception('Table '.$this->tablename.' could not be loaded');
   endif;
 } catch(SF_localization_exception $ex){$ex->trace(TRUE);$ex->__exit();}
 
 $tbl = array();
 $i = 0;
 
 while ($i < count($buf) ) :
   if (preg_match('/"(.*)"+[ = ]+"(.*)";+$/',trim($buf[$i]),$row) && !preg_match("/^[\/\/|\/\*]/",$buf[$i])) :
     $tbl[$row[1]] = $row[2];
   endif;
   $i++;
 endwhile;
 
 $this->table = $tbl;
 
 unset($tbl,$buf);
}
