pg_lo_import

(PHP 4 >= 4.2.0, PHP 5)

pg_lo_import -- Import a large object from file

Popis

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.

Poznámka: Pokud je zapnut bezpečný režim (safe-mode), PHP kontroluje, zda soubory/adresáře, se kterými pracujete, mají stejné UID jako spuštěný skript.

Poznámka: This function used to be called pg_loimport().
