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: When safe mode is enabled, PHP checks whether the files or directories being operated upon have the same UID (owner) as the script that is being executed.
Note:
This function used to be called pg_loimport().
Parameters
- 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.
- object_id
-
If an object_id is given the function will try to create a large object with this id, else a free object id is assigned by the server. The parameter was added in PHP 5.3 and relies on functionality that first appeared in PostgreSQL 8.1.
Return Values
The OID of the newly created large object, or FALSE on failure.
