pg_lo_import
(PHP 4 >= 4.2.0, PHP 5)
pg_lo_import — Import a large object from file
LeÃrás
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: Ha a safe mode be van kapcsolva, a PHP ellenÅ‘rzi, hogy az állományok vagy könyvtárak, amelyekkel dolgozni szeretnél, ugyanazzal a felhasználói azonosÃtóval (UID) rendelkeznek-e, mint az éppen futó program.
Note: This function used to be called pg_loimport().
Paraméterek
- 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.
Visszatérési értékek
The OID of the newly created large object, or FALSE on failure.
