Re: Array function to delete

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) ?> -Kevin ----- Original Message ----- From: "Liam Gibbs" <liamgibbs@yahoo.com> To: <php-general@lists.php.net> Sent: Thursday, April 25, 2002 2:27 PM Subject: Re: [PHP] Array function to delete > Thanks for all your help, everyone, but both > suggestions (unset and array_slice) pretty much didn't > improve on my current way.
