pg_freeresult

Name

pg_freeresult — Frees query memory.

Synopsis

string pg_freeresult(result); int result: Result identifier

Returns

TRUE on success; FALSE on error

Description

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

Example 1040. Free query memory

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