how to empty an array??

[newtoall]

I have an array being created a number of times with in a loop, before it is created I want to check if it empty and if it isn't then clear it down. How do I do this??

 

Any help you can provide will help preserve my sanity.

if(!empty($array)) $array=array();

You can use the [http://www.php.net/unset]unset()[/url] function and then recreated it. Just recreating it works find too.

<?php
$tst = array('test','test1','test2','test3');
echo 'Before: <pre>' . print_r($tst,true) . '</pre>';
unset($tst);
$tst = array();
echo 'After: <pre>' . print_r($tst,true) . '</pre>';
?>
