pg_close() closes the non-persistent
connection to a PostgreSQL database associated with the given
connection resource.
Note:
Using pg_close() is not usually necessary, as
non-persistent open connections are automatically closed at the end
of the script.
If there is open large object resource on the connection, do not
close the connection before closing all large object resources.
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().
Return Values
Returns TRUE on success or FALSE on failure.
Examples
Example 1. pg_close() example
<?php $dbconn = pg_connect("host=localhost port=5432 dbname=mary") or die("Could not connect"); echo "Connected successfully"; pg_close($dbconn); ?>
