# pg_lo_open

(PHP 4 >= 4.2.0)

pg_lo_open -- Open a large object

## Description

resource pg_lo_open ( resource connection, int oid, string mode)

pg_lo_open() opens a Large Object and returns large object resource. The resource encapsulates information about the connection. `oid` specifies a valid large object oid and `mode` can be either "r", "w", or "rw". It returns `FALSE` if there is an error.

Warning
Do not close the database connection before closing the large object resource.

To use the large object (lo) interface, it is necessary to enclose it within a transaction block.

> Note: This function used to be called `pg_loopen()`.

See also pg_lo_close() and pg_lo_create().
