(PHP 4 >= 4.2.0, PHP 5)

pg_lo_importImport a large object from file

Descrierea

int pg_lo_import ([ resource $connection ], string $pathname [, mixed $object_id ] )

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.

Notă: Când este activat modul securizat, PHP verifică dacă fișierele și directoarele cu care se va opera au același UID (proprietar) ca și script-ul care se execută.

Notă:

This function used to be called pg_loimport().

Parametri

pathname
