pg_lo_import

(PHP 4 >= 4.2.0, PHP 5)

pg_lo_importImport a large object from file

Descripción

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.

Nota: Cuando safe mode está habilitado, PHP comprueba si los archivos o directorios que va a utilizar tienen el mismo UID (propietario) que el script que está siendo ejecutado.

Nota:

This function used to be called pg_loimport().

Parámetros

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.

object_id

If an object_id is given the function will try to create a large object with this id, else a free object id is assigned by the server. The parameter was added in PHP 5.3 and relies on functionality that first appeared in PostgreSQL 8.1.

Valores devueltos

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