在for循环中增加变量名称

Question

so I have a variable that I would like to set based on some submitted form data. On the form I have a set of fields that the user can increase the number of (that is, they can add more of the same type of field), and so I need to set the script that handles the submitted data to accomodate this.

So far this is what I have:

while ($i <= $totalproducts) {

       $product.$i = $_POST['product'.$i];
       $i++;

    }

$totalproducts holds the total number of fields. As an example, let's say I had 3 items, here's what I would like to get from the code:

$product1 = $_POST['product1'];
$product2 = $_POST['product2'];
$product3 = $_POST['product3'];

I'm sure I'm close, just can't quite slot it together...

You can use variable variable:

while ($i <= $totalproducts) {
   $variable = 'product' . $i;

   $$variable = $_POST['product' . $i];
   $i++;
}

But better will be use array:

$products = array();
while ($i <= $totalproducts) {
   $products[$i] = $_POST['product' . $i];
   $i++;
}
