pg_free_result

Free result memory

Description

bool pg_free_result(PgSql\Result $result)

pg_free_result frees the memory and data associated with the specified PgSql\Result instance.

This function need only be called if memory consumption during script execution is a problem. Otherwise, all result memory will be automatically freed when the script ends.

Note:

This function used to be called pg_freeresult.

Parameters

result

An PgSql\Result instance, returned by pg_query, pg_query_params or pg_execute(among others).

Return Values

Returns true on success or false on failure.

Changelog

Version Description
8.1.0 The result parameter expects an PgSql\Result instance now; previously, a resource was expected.

Examples

Example #1 pg_free_result example

<?php
$db = pg_connect("dbname=users user=me") || die();

$res = pg_query($db, "SELECT 1 UNION ALL SELECT 2");

$val = pg_fetch_result($res, 1, 0);

echo "First field in the second row is: ", $val, "\n";

pg_free_result($res);
?>

The above example will output:

First field in the second row is: 2
