$object_id
) pg_lo_create() creates a large object and returns the OID of the large object. 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).
To use the large object interface, it is necessary to enclose it within a transaction block.
Instead of using the large object interface (which has no access controls and is cumbersome to use), try PostgreSQL's bytea column type and pg_escape_bytea().
Note:
This function used to be called pg_locreate().
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().
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.
A large object OID or FALSE
on error.
The optional object_id
was added.
