Remove Objects From Array With Unset

[kvarnerexpress 0]

Have been trying to solve this for a long time now, so I thought I´d give you guys a chance to break it!

I want to remove an object from an array that I store in a Session object. I´ve 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 it´s supposed to remove it. Quite simple, that´s why I cant see why it doesnt work!

Here´s the 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!

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.php

Hope this helps some~

Note the line:

 

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.
