"'");             $itemarray = array($productbycode[0]["id"]=>array('name'=>$productbycode[0]["product_name"], 'id'=>$productbycode[0]["id"], 'quantity'=>$qty, 'price'=>$productbycode[0]["new_price"]));              $itemexists = checkcartforitem($additem, $_session['cart_item']);               if ($itemexists !== false){                   $_session['cart_item'][$itemexists]['quantity'] = $qty ;              } else {                   if(!empty($_session["cart_item"])) {                      if(in_array($productbycode[0]["id"],$_session["cart_item"])) {                         foreach($_session["cart_item"] $k => $v) {                                 if($productbycode[0]["id"] == $k)                                     $_session["cart_item"][$k]["quantity"] = $qty;                         }                     } else {                         $_session["cart_item"] = array_merge($_session["cart_item"],$itemarray);                     }                 } else {                     $_session["cart_item"] = $itemarray;                 }                }          }     break;     case "remove":         if(!empty($_session["cart_item"])) {             foreach($_session["cart_item"] $k => $v) {                     if($_get["id"] == $k)                         unset($_session["cart_item"][$k]);                           if(empty($_session["cart_item"]))                         unset($_session["cart_item"]);             }         }      break;     case "empty":         unset($_session["cart_item"]);     break;   } }

array (print_r($_session["cart_item"]);)

array ( [0] => array ( [name] => sadfsafsadf [id] => 11 [quantity] => 1 [price] => safsafsa ) [1] => array ( [name] => tp-link 4 port wireless dual band n600 [id] => 13 [quantity] => 1 [price] => 15980 ) )

you made mistake on line. if($_get["id"] == [$k])

 case "remove":         if(!empty($_session["cart_item"])) {             foreach($_session["cart_item"] $k => $v) {                     if($_get["id"] == $_session["cart_item"][$k]['id'])                         unset($_session["cart_item"][$k]);                           if(empty($_session["cart_item"]))                         unset($_session["cart_item"]);             }         }      break;
