unset()

[Anon]

Stange thing Ive noticed.

<?
$test[0] = 'a';
$test[1] = 'b';
$test[2] = 'c';
unset($test[0]);
unset($test[1]);
unset($test[2]);

if (isset($test))
// this is true

unset($test);

if (isset($test))
//this is false
?>

What I would have though was that If I delete all the elements of an array, then wouldnt the variable no longer exist?

An array can have zero elements, as for example if you
do the following:

&nbsp;&nbsp;$colors = array();
