Default array gone wrong.

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.

try
PHP Code:
<?php
$priceids 
$row_call_albums['priceids'];
$arr = array($priceids);
print_r($arr);
/*foreach ($arr as $value) {
   $value = $value * 2;
   echo $value;
}*/
?>
if it gives you an array then?

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

This is my result when I put
print_r($arr);

Array ( [0] => 1, 2, 3 )

And when I tried $arr as $key => $value, gave me the same result as before. Just plain 2.

the fix is
PHP Code:
<?php
$priceids 
$row_call_albums['priceids'];
$arr explode(" "$priceids);
foreach (
$arr as $key => $value)
{
   
$key $value 2;
   echo 
$key;
}
?>

You can cut out a line of code by just using this.

PHP Code:
$arr explode(' '$row_call_albums['priceids']); 
No sense adding another variable to memory when it's not needed.

Actually, if the rusults of $row_call_albums['priceids'] has the format of 1, 2, 3 then you should explode it into array with ',' not ' '.

Since they are comma seperated the explode should be using a comma, not a space ;

Quote:
$arr = explode(",", $priceids);
