array gone wrong.

[Red Blaze]

This is the little piece of code I'm trying to get working.

PHP Code:

<?php
$priceids = $row_call_albums['priceids'];
$arr = array($priceids);
foreach ($arr as $value) {
   $value = $value * 2;
   echo $value;
}
?>

In this case, $priceids calls 1, 2, 3.

Now, it does call it, but it doesn't loop. It does 1x2, and stops there. But if I replace "$priceids" with "1, 2, 3", it works just fine. It multiplies 1x2, then 2x2, then 3x2.

The results with $priceids in the array is just "2". But the results for "1, 2, 3" in the array is "246".

Is there a way around this issue? Thanks in advance.
