PHP : Function Reference : PostgreSQL Functions : pg_lo_import

pg_lo_import

Import a large object from file (PHP 4 >= 4.2.0, PHP 5)
int pg_lo_import ( resource connection, string pathname )
int pg_lo_import ( string pathname )

pg_lo_import() creates a new large object in the database using a file on the filesystem as its data source.

To use the large object interface, it is necessary to enclose it within a transaction block.

Note:

When safe mode is enabled, PHP checks whether the files or directories you are about to operate on have the same UID (owner) as the script that is being executed.

Note:

This function used to be called pg_loimport().

Parameters

connection

PostgreSQL database connection resource. When connection is not present, the default connection is used. The default connection is the last connection made by pg_connect() or pg_pconnect().

pathname

The full path and file name of the file on the client filesystem from which to read the large object data.

Return Values

The OID of the newly created large object, or FALSE on failure.

ChangeLog

Version Description
4.2.0

The syntax of this function changed. It used to be:

Examples

Example 1946. pg_lo_import() example

<?php
  $database
= pg_connect("dbname=jacarta");
 
pg_query($database, "begin");
 
$oid = pg_lo_import($database, '/tmp/lob.dat');
 
pg_query($database, "commit");
?>

its not very clear if pg_lo_import needs to have pg_lo_open called first. Because pg_lo_import handles the process of writign to the file, it seems logical that pg_lo_open does not need to be called. However due to the ugly nature of how postgres handles oid objects, it would be nice to have this documented.

ceco

it works for me (php-4.2.1)
not like this
int pg_lo_import ( string pathname [, resource connection])
but
int pg_lo_import ( resource connection, string pathname )
don't know the reason

Due to a bug, PHP 4.2.0 and 4.2.1 does not support pg_lo_import() old API. It's fixed in PHP 4.2.2.
BTW, new API will be always available from PHP 4.2.0 to later versions. Older API will be kept long enough, also.
