Now do you want (1, 2, 4, 5) or (1, 2, 3,4 ) ? If second: So you want the array always to contain a continuous list of numbers (1..n) ? So it's irrelevant *what* element of the array you delete, only *how many* elements you delete? Why not just store the maximum value then and use $MaxVal-- instead of unset ($a[something]), $Index - 1 instead of $a[$Index] ? If the first: remember that arrays in PHP are always associative. So you get (0 => 1, 1 => 2, 3 => 4, 4 => 5) if you want the keys "reordered" you could use array_values() on that.. -- Christian Reiniger LGDC Webmaster (http://lgdc.sunsite.dk/) "Never doubt that a small group of thoughtful, committed people can change the world...
