pg_lo_create — Create a large object
pg_lo_create() creates a large object and returns the OID of the large object. PostgreSQL access modes
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().
This function used to be called pg_locreate().
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.
Example #1 pg_lo_create() example
$database = pg_connect("dbname=jacarta");
$oid = pg_lo_create($database);
$handle = pg_lo_open($database, $oid, "w");
pg_lo_write($handle, "large object data");
