Question

I have problem in deleting an element of array. Look:

<?php
session_start();
$i = 0;
$expected = $_GET['name'];
foreach($_SESSION['chart'] as $name)
{
     if($name==$expected)
     {
         break;
     }
     $i++;
}
unset($_SESSION['chart'][$i]);

echo count($_SESSION['chart'])." ".$expected." ".$i;
//echo "<script>history.go(-1);</script>";
?>

I’m getting this output: 3 name 2.

I know that element in array exists with name ‘name’, but I can’t unset it. Please help me.

Why not let PHP do the search?

<?php
session_start();
$key = array_search($_GET['name'], $_SESSION['chart']);
if ($key !== false) {
   unset($_SESSION['chart'][$key]);
}
