# pg_lo_create

(PHP 4 >= 4.2.0, PHP 5)

pg_lo_create -- Create a large object

## Description

int pg_lo_create ( [resource connection] )

pg_lo_create() creates a Large Object and returns the oid of the large object. connection specifies a valid database connection opened by pg_connect() or pg_pconnect(). PostgreSQL access modes INV_READ, INV_WRITE, and INV_ARCHIVE are not supported, the object is created always with both read and write access. INV_ARCHIVE has been removed from PostgreSQL itself (version 6.3 and above). It returns large object oid, otherwise it returns `FALSE` if an error occurred.

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

> 注: This function used to be called pg_locreate().
