(PHP 4 >= 4.2.0, PHP 5)

pg_lo_import -- Import a large object from file


int pg_lo_import ( resource connection, string pathname )

int pg_lo_import ( string pathname )

In versions before PHP 4.2.0 the syntax of this function was different, see the following definition:

int pg_lo_import ( string pathname [, resource connection] )

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().



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().


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.


Example 1. pg_lo_import() example

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