pg_lo_import — Import a large object from file

설명

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.

Note: 안전 모드일 때, PHP는 조작하려는 파일이나 디렉토리가 실행중인 스크립트와 같은 UID(owner)인지 확인합니다.

This function used to be called pg_loimport().
