[SOLVED] Remove an item from an array?

[Solarpitch]

Hey,

 

I have the floowing code to add an id to an array but how can I remove an id from the array if I needed?

 

<?php

	$id = $_GET['id'];

	if(!is_array($_SESSION['compare']))
	{
	  $_SESSION['compare'] = array();
	  }

	if(!in_array($id, $_SESSION['compare']))
	{
	  $_SESSION['compare'][] = $id;
	}


?>

Thanks but I already did. See, I'm using unset in the below context but instead of removing the id, it removes all of the id's which I cant find the solution to on that page

 

<?php

unset($id, $_SESSION['compare']);

?>

[premiso]

unset($_SESSION['compare'][array_search($id, $_SESSION['compare'])]);

 

Should get you the desired result.
