pg_lo_create
Create a large object
(PHP 4 >= 4.2.0, PHP 5)
int pg_lo_create ( [resource connection] )
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().
This function used to be called pg_locreate().
Parameters
- 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().
Examples
Example 1944. pg_lo_create() example

$database = pg_connect("dbname=jacarta");
pg_query($database, "begin");
$oid = pg_lo_create($database);
echo "$oid\n";
$handle = pg_lo_open($database, $oid, "w");
echo "$handle\n";
pg_lo_write($handle, "large object data");
pg_lo_close($handle);
pg_query($database, "commit");
?>
