php - Deleting from an array

i have an array that looks like this:

Array ( 

    [0] => Array ( 
        [id] => 18 
        [name] => book 
        [description] => 
        [quantity] => 0 
        [price] => 50 
        [status] => Brand New
    ) 
    [1] => Array ( 
        [id] => 19 

        [name] => testing   
        [description] => for testing 
        [quantity] => 2 
        [price] => 182 
        [status] => Brand New
    ) 
    [2] => Array ( 
        [id] => 1 
        [name] => Fruity Loops 
        [description] => dj mixer 

        [quantity] => 1     
        [price]  => 200 
        [status] => Brand New
    ) 
)

I want to be able to delete an entire row in the array (when a user clicks a delete link) say array[1] which is:

[1] => Array ( 

    [id] => 19 
    [name] => testing   
    [description] => for testing 
    [quantity] => 2 
    [price] => 182 
    [status] => Brand New
)

I have this code where i'm trying to delete based on the id of the product but it doesn't work

//$_SESSION['items'] is the array and $delid is the "product id" gotten when a user clicks  delete on a particular row.
foreach ($_SESSION['Items'] as $key => $products) { 
    if ($products['id'] == $delid) {
        unset($_SESSION['Items'][$key]);
    }
}

How do i implement this? Thanks

Answer

You could pass $_session into an ArrayIterator and use ArrayIterator::offsetUnset().

For example:-

session_start();

$_SESSION['test1'] = 'Test1';
$_SESSION['test2'] = 'Test2';
$_SESSION['test3'] = 'Test3';


var_dump($_SESSION);
$iterator = new ArrayIterator($_SESSION);
$iterator->offsetUnset('test2');
$_SESSION =  $iterator->getArrayCopy();

var_dump($_SESSION);

Output:-

array (size=3)
  'test1' => string 'Test1' (length=5)
  'test2' => string 'Test2' (length=5)
  'test3' => string 'Test3' (length=5)

array (size=2)
  'test1' => string 'Test1' (length=5)
  'test3' => string 'Test3' (length=5)

This also saves you the expense of looping through the array to find the element you want to delete.
