Apparently in 4.1.X this is true... I'd been running 4.0.6 for a long time (until
4.1.2 was
released), and must have coded it in the earlier version. I stand corrected! :-)
A simple test to see if your version supports this:
<?php
$array = array();
$array[0] = "zero";
$array[1] = "one";
$array[2] = "two";
$array[3] = "three";
unset($array[1]);
foreach ($array as $key=>$value) {
echo $key." = ".$value."<BR>";
}
?>
If you're running an older version, it should output:
0 = zero
1 =
2 = two
3 = three
Versions 4.1.X+ should completely remove key 1.

You need to upgrade. :) The above hasn't been true for a while...at
least since 4.1.2 and perhaps earlier.
