如何取消或删除$ _SESSION中的一些嵌套数组

Question

I have some items in shop basket in SESSION.

Each item maybe be for one shop and another item maybe for another shop.

I want when customer click in create factor button for each shop item list in basket. How can I delete or unset some items in my basket that have same shopid and customer click create factor for this shop with this shopid.

My session array for example is:

Array('customer' => Array('basket' => Array(
                    '9_2' => Array
                        (
                            "row" => "0",
                            'item' => 'cd',
                            'count' => '1',
                            'sale_start_date' => '1391-12-25 19:27:56',
                            'sale_end_date' => '1392-04-20 19:27:49',
                            'sale_price' => '40500',
                            'price' => '54564',
                            'id' => '999035',
                            'shopid' => '4'
                        ),
                        '999_17' => Array
                        (
                            'row' => '1',
                            'item' => 'car',
                            'count' => '1',
                            'sale_start_date' => '0000-00-00 00:00:00',
                            'sale_end_date' => '0000-00-00 00:00:00',
                            'sale_price' => '0',
                            'price' => '520000',
                            'id' => '999039',
                            'code' => 'b125nh',
                            'shopid' => '6'
                        ),
                        '9_3' => Array
                        (
                            'row' => '2',
                            'item' => 'book',
                            'count' => '1',
                            'sale_start_date' => '0000-00-00 00:00:00',
                            'sale_end_date' => '0000-00-00 00:00:00',
                            'sale_price' => '0',
                            'price' => '520000',
                            'id' => '999039',
                            'code' => 'b125nh',
                            'shopid' => '4'
                        ),
                        '10_5' => Array
                        (
                            'row' => '2',
                            'item' => 'dvd',
                            'count' => '1',
                            'sale_start_date' => '0000-00-00 00:00:00',
                            'sale_end_date' => '0000-00-00 00:00:00',
                            'sale_price' => '0',
                            'price' => '520000',
                            'id' => '999039',
                            'code' => 'b125nh',
                            'shopid' => '5'
                        )
                    )
                )
            );

You can see some items are with different shopid and it's not sort.

How can delete, for example, those items with shopid=4 from my basket?

Answer 1

Using a simple loop and built in PHP array functions:

$deleteShopId = 4;
$test = Array('customer' => Array('basket' => Array(
                    '9_2' => Array
                        (
                            "row" => "0",
                            'item' => 'cd',
                            'count' => '1',
                            'sale_start_date' => '1391-12-25 19:27:56',
                            'sale_end_date' => '1392-04-20 19:27:49',
                            'sale_price' => '40500',
                            'price' => '54564',
                            'id' => '999035',
                            'shopid' => '4'
                        ),
                        '999_17' => Array
                        (
                            'row' => '1',
                            'item' => 'car',
                            'count' => '1',
                            'sale_start_date' => '0000-00-00 00:00:00',
                            'sale_end_date' => '0000-00-00 00:00:00',
                            'sale_price' => '0',
                            'price' => '520000',
                            'id' => '999039',
                            'code' => 'b125nh',
                            'shopid' => '6'
                        ),
                        '9_3' => Array
                        (
                            'row' => '2',
                            'item' => 'book',
                            'count' => '1',
                            'sale_start_date' => '0000-00-00 00:00:00',
                            'sale_end_date' => '0000-00-00 00:00:00',
                            'sale_price' => '0',
                            'price' => '520000',
                            'id' => '999039',
                            'code' => 'b125nh',
                            'shopid' => '4'
                        ),
                        '10_5' => Array
                        (
                            'row' => '2',
                            'item' => 'dvd',
                            'count' => '1',
                            'sale_start_date' => '0000-00-00 00:00:00',
                            'sale_end_date' => '0000-00-00 00:00:00',
                            'sale_price' => '0',
                            'price' => '520000',
                            'id' => '999039',
                            'code' => 'b125nh',
                            'shopid' => '5'
                        )
                    )
                )
            );

foreach($test['customer']['basket'] as $something => $somethingElse){
$temp = array_search($deleteShopId,$somethingElse);
   if($temp !== FALSE && $temp =='shopid'){
      unset($test['customer']['basket'][$something]);
   }
}

var_dump($test['customer']['basket']);

output:

array(2) {
  ["999_17"]=>
  array(10) {
    ["row"]=>
    string(1) "1"
    ["item"]=>
    string(3) "car"
    ["count"]=>
    string(1) "1"
    ["sale_start_date"]=>
    string(19) "0000-00-00 00:00:00"
    ["sale_end_date"]=>
    string(19) "0000-00-00 00:00:00"
    ["sale_price"]=>
    string(1) "0"
    ["price"]=>
    string(6) "520000"
    ["id"]=>
    string(6) "999039"
    ["code"]=>
    string(6) "b125nh"
    ["shopid"]=>
    string(1) "6"
  }
  ["10_5"]=>
  array(10) {
    ["row"]=>
    string(1) "2"
    ["item"]=>
    string(3) "dvd"
    ["count"]=>
    string(1) "1"
    ["sale_start_date"]=>
    string(19) "0000-00-00 00:00:00"
    ["sale_end_date"]=>
    string(19) "0000-00-00 00:00:00"
    ["sale_price"]=>
    string(1) "0"
    ["price"]=>
    string(6) "520000"
    ["id"]=>
    string(6) "999039"
    ["code"]=>
    string(6) "b125nh"
    ["shopid"]=>
    string(1) "5"
  }
}

Of course rename $something and $somethingElse to something more meaningful. I have no idea what they represent.
