Have been trying to solve this for a long time now, so I thought Iīd give you guys a chance to break it! I want to remove an object from an array that I store in a Session object. Iīve written a function that takes an array and an id as parameters. Checks if one of the objects has the id I want to remove and then itīs supposed to remove it. Quite simple, thatīs why I cant see why it doesnt work! Hereīs the code: CODE function Remove_prod($id2,$AL) { print_r($AL); foreach ($AL as $prod) if($prod->id == $id2) { echo "REMOVING!<p><p>"; unset($AL[$prod]); } print_r($AL); return $AL; } I get the same data before and after the execution of the code. I know that the unset function is executed but no value is changed. So, what say you? Thanks in advance! kvarnerexpress

I would suggest that you actually read the PHP documentation about the unset() function. Here's the link: http://us3.php.net/manual/en/function.unset.phpHope this helps some~

Note the line: CODE if($prod->id == $id2) The '$prod' variable is not an object, yet here you are treating it as if it were. This would cause problems. I'm not sure exactly what 'id' is supposed to be, but if the array '$AL' contains arrays within itself, each with an inded 'id', try replacing '$prod->id' with '$prod['id']'. It would help a lot if you could give an example of the structure of the '$AL' array. How many dimensions, is it numerically or associatively indexed, what is the data it contains, etc. A simple var_dump() would be sufficient.

Array Pointers Can Be Backwards
(Kind of) (8) I just found this out today: When you're using arrays, when you reference a certain index, you
can switch the pointer and the subscript around. I know I'm not explaining that very good, but
here's and example: CODE int a[] = {1,2,3,4,5,6,7,8,9,10,11}; int b =1; int
c[] = {0,-5,11,0,0,5,0,0,0}; cout << b[a][c]; //Same as
c[a[b]]; See? 'b' is actually just an integer, it's not an array,
or pointer, or anything. Usually, you would have to put the array first, then an integer. Like....
[ruby]lite Multi-dimensional Array
(0) Hey everyone, What I have here is a really simple Multi-Dimensional Array class. This is a Lite

Flash - Streaming Flv With Interactible Objects
Actionscript 3.0 - syncronising swf with flv (3) Hi Guys, I am trying to make a flash based web site. The idea is to have a flv video streaming

video by importing the flv to the flash time line and creating a button that follows a person in
each frame. I then remove the flv video from the timeline and stream it using actionscript. This
leads to synchronization issues. Does anyone know if this combination of swf and flv has ever been
