Version specific PHP code?

I dont believe php 4 supports references in a foreach construct, which you shouldnt being using regardless.

The nature of foreach is to use a copy of an array and go through it key by key, if you want to operate on references, it would be better to use a for construct

$keys = count($array);
for ($i=0;$i<=$keys;$i++)
{
$option = &$array[$i];
}

and so on
