<?php
$old_array= array('one','two','three','four');
$new_array= array();
foreach($old_array as $value){
$new_array= $value;
}
echo "$new_array";
?>
The result of the echo is "four". Doing the same above with the [] after
new_array returns the right result, a new array.(outputs Array). So what
exactly where you saying 'Taint so' Al? I'm confused since Jochem's
email about how to properly copy an array seems correct.
