pg_freeresult — Frees query memory.


string pg_freeresult(result);
int result: Result identifier


TRUE on success; FALSE on error


pg_freeresult() can be used as a memory cleaner at any time after a query is run. All query results are stored in memory and then retrieved from memory when necessary. If you're concerned that your query may use too much memory in your script, calling pg_freeresult() will free the result memory. You really only need this if you're going to be making lots of queries in a script or if your query returns large amounts of data.


Example 1040. Free query memory

$db = pg_connect("host=dbserver dbname=db user=dbuser password=dbpasswd");
$result = pg_exec($db,"SELECT * FROM employees");
