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)
?>
