pg_lo_import
(PHP 4 >= 4.2.0, PHP 5)
pg_lo_import — Import a large object from file
Popis
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: Keď je safe mode povolený, PHP zisťuje, či súbory alebo adresáre, na ktorých idete pracovať, majú rovnaké UID (vlastník) ako skript, ktorý sa spracováva.
Note: This function used to be called pg_loimport().
