About all I would suggest is that you eliminate the unecessary function
calls substr and explode to optimize your code.  I doubt prebuilt PHP
functions will help you here.  This is perfectly valid method for deleting
elements in an array and it's about as fast as you're ever going to get.  :)

<?
$listitems = array ('grill', 'bar', 'foo', 'world');
$item_to_delete = 'foo';

// Loop through listitems array.
for ($i=0; $i<count($listitems); $i++)
{
    // Ignore item to delete.
    if ($listitems[$i] != $item_to_delete)
    {
        // Save all other items in tmplist array.
        $tmplist[] = $listitems[$i];
    }
}
$listitems = $tmplist;  //new array contains (grill, bar, world)
?>
