php foreach with if loop through array of objects performing if condition times members in array instead of only once

Question

$_SESSION['quantity'] is an array of Objects.

let's say I already added a product with id = 1 to the array.

Next I add same product with id = 1 , so now $sameProduct = 1 and is set.

$q->update() increments by the property 'quantity' of that object by 1.

The code works well when there is only one item in the array, the problem starts when there are more than one item. The code runs times there items in the array instead of only once for that particular object.

   <?php 
if(!session_start()){session_start();}

require_once 'components/sql_login.php';
require_once 'components/header.php';

if(isset($_SESSION['userSession']) != ""){
    echo "<script> window.location.href = 'user/cart.php'; </script>";
    }

if(!isset($_SESSION['productIds'])){$_SESSION['productIds']=array();}
if(!isset($_SESSION['cartProducts'])){$_SESSION['cartProducts']=array();}
if(!isset($_SESSION['quantity'])){$_SESSION['quantity']=array();}

if (isset($_GET['f'])){ 
    if(!in_array($_GET['f'],$_SESSION['productIds'])){
    $newFairy = $_GET['f'];
    array_push($_SESSION['productIds'],$newFairy);

        } else {$oldFairy = $_GET['f'];}
    }


    foreach($_SESSION['productIds'] as $newItem){
    $query = "SELECT * FROM products WHERE id = ?";
    if($getFairy = $sqlConnection->prepare($query)){
        $getFairy->bind_param("i",$newItem);
        $getFairy->execute();
        $result = $getFairy->get_result();
        $row    = $result->fetch_array();
        $getFairy->close();

            $newProduct = new AddProduct($row);
            }

Answer 1

try to put a break, and only do once whn firs concurrence:

$founded = false;
    foreach($_SESSION['quantity'] as $q){
    if($q->id == $sameProduct && !$founded){     
    $q->update();
$founded=true;
    return $founded;
        }
    }

Putting a semaphore, could be done, and try to look with a return stops the foreach

Answer 2

is it for you possible to use the id of your product as array key?

Like :

$_SESSION['quantity'][$sameProduct]

In this case you dont need to loop $_SESSION['quantity']

Answer 3

"break 2;" did it! the code:

    if(isset($existingProduct) != ""){
                foreach($_SESSION['quantity'] as $q){
                    if($existingProduct == $q->id){     
                    $q->update();
                    print_r($_SESSION['quantity']);
                    break 2;
                        }
                    }
                }

post answer #103:

" As stated in other posts, you can use the break keyword. One thing that was hinted at but not explained is that the keyword can take a numeric value to tell PHP how many levels to break from.

For example, if you have three foreach loops nested in each other trying to find a piece of information, you could do 'break 3' to get out of all three nested loops. This will work for the 'for', 'foreach', 'while', 'do-while', or 'switch' structures.
