pg_lo_import — Import a large object from file
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().
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().
pathnameThe 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.
The OID of the newly created large object, or
FALSE on failure.
