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.
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'];
?>
