mysql_free_result
(PHP 4, PHP 5, PECL mysql:1.0)
mysql_free_result — Free result memory
Description
bool mysql_free_result
( resource $result
)
mysql_free_result() only needs to be called if
you are concerned about how much memory is being used for queries
that return large result sets. All associated result memory is
automatically freed at the end of the script's execution.
Parameters
-
result
-
The result resource that
is being evaluated. This result comes from a call to
mysql_query().
Return Values
Returns TRUE on success or FALSE on failure.
If a non-resource is used for the result
, an
error of level E_WARNING will be emitted. It's worth noting that
mysql_query() only returns a resource
for SELECT, SHOW, EXPLAIN, and DESCRIBE queries.
Examples
Example #1 A mysql_free_result() example
<?php
$result = mysql_query("SELECT id,email FROM people WHERE id = '42'");
if (!$result) {
echo 'Could not run query: ' . mysql_error();
exit;
}
/* Use the result, assuming we're done with it afterwards */
$row = mysql_fetch_assoc($result);
/* Now we free up the result and continue on with our script */
mysql_free_result($result);
echo $row['id'];
echo $row['email'];
?>
