1.2.741. Multiple Unset()¶
Unset() accepts multiple arguments, unsetting them one after each other. It is more efficient to call unset() once, than multiple times.
<?php
// One call to unset only
unset($a, $b, $c, $d);
// Too many calls to unset
unset($a);
unset($b);
unset($c);
unset($d);
?>
See also unset.
