PHP - Can not display the results by key in foreach loop

Question

Here is my code:

$stack = array();
foreach ($quote->getAllItems() as $item) {
       $PID = $item->getProduct()->getId();
        $stack["productid"][] = $PID;
        $QTY = $item->getQty();
        $stack["productqty"][] = $QTY;

}


foreach($stack as $value){
 $ProductId = $value["productid"];
 $ProductQty = $value["productqty"];
 echo "ProductId is: $ProductId - Product QTY is: $ProductQty <br>";
}

I receive two rows as the exact number of results is but $ProductId and $ProductQty seems to be blank.

Where is my mistake why i can not display the results by key?

Thanks in advance!

Can you please make a complete answer so i can test and mark it ? — Venelin

 if(!empty($stack) && count($stack)>0)
 {
     foreach($stack['productid'] as $key=>$value){
         $ProductId = $value;
         $ProductQty = $stack["productqty"][$key];
         echo "ProductId is: $ProductId - Product QTY is: $ProductQty <br>";
     }
 }

Use this code..

You just try with below code

foreach($stack as $value){
     $ProductId = $value[0];
    $ProductQty = $value[1];
    echo "ProductId is: $ProductId - Product QTY is: $ProductQty <br>";
 }

The reason is, in the first iteration, the $value will contain the value of $stack["productid"]. So that $value["productid"] won't work. You have to give the index 0. And for the $ProductQty you have to give index 1

Not working. the result is: ProductId is: 30029 - Product QTY is: 30030 ProductId is: 1 - Product QTY is: 3 which is not corect. QTY for the first item is 1, for the second is 3.

Try this code. it will help full....

foreach ($quote->getAllItems() as $item) {
        $stack[] = array('productid'=>$item->getProduct()->getId(),'productqty'=>$item->getQty());
}

foreach($stack as $value){ 

     $ProductId = $value["productid"];
     $ProductQty = $value["productqty"];
     echo "ProductId is: $ProductId - Product QTY is: $ProductQty <br>";

}
