pg_lo_import
(PHP 4 >= 4.2.0, PHP 5)
pg_lo_import — Import a large object from file
Description
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: 當安全模式開啟,PHP會檢查執行的腳本和要操作的檔案或目錄是否有相同的UID(擁有者)。
Note: This function used to be called pg_loimport().

-
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.
Return Values
The OID of the newly created large object, or FALSE on failure.
