Leírás

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:

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.

Megjegyzés: Ha a safe mode be van kapcsolva, a PHP ellenőrzi, hogy az állományok vagy könyvtárak, amelyekkel dolgozni szeretnél, ugyanazzal a felhasználói azonosítóval (UID) rendelkeznek-e, mint az éppen futó program.

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