从数组中删除[重复]

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

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.

there seems no problem with the way you are doing the delete. But I think the problem is in the structure of the array. For example, string values are not quoted, there are no commas separating array items, and the array keys are written within [].

Try changing your array as below and the delete should work fine:

$_SESSION['Items'] = 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'
    ) 
);

Hope it helps.
