how to add the integer values using foreach in php

Question

I just want to know the syntax of adding the quantity using foreach. Any help is greatly appreciable.

Here is the code what I do so far:

$qproducts = '0';
foreach ($this->cart->getProducts() as $product) {  
    $qproducts .= $product['quantity'];
}       
$this->data['pquantity'] = $qproducts;

You mean like this?

$qproducts = 0;
foreach ($this->cart->getProducts() as $product) {  
    $qproducts += $product['quantity'];
}       
$this->data['pquantity'] = $qproducts;

Use + (addition) instead of . (concatenation).

$qproducts = 0;
foreach ($this->cart->getProducts() as $product) {  
    $qproducts += $product['quantity'];
}
