Explode Unknown amount of variables

I have a string of data which is an unknown length eg $myvar = "data,data"; and i want to explode the string eg list($a, $b) = explode(",", $myvar) which works great if I know the length of the data, but im not sure how to handle variable lengths.

i was thinking of using if statments.

eg: $letter_count = substr_count($myvar, ','); 

if($letter_count == 2) { list($a, $b) = explode(",", $myvar) }
elseif($letter_count == 3) { list($a, $b, $c) = explode(",", $myvar) }

but this is not practical, anyone got any ideas how else i could do this?

If you use explode, it will return an array that is split by your delimiter. You would then call each item by its index position. The following example uses a space as the delimiter.

$pizza  = "piece1 piece2 piece3 piece4 piece5 piece6";
$pieces = explode(" ", $pizza);
echo $pieces[0]; // piece1
echo $pieces[1]; // piece2

just explode into a regular array reference:

$return = explode("," $myvar);

The format you're using is for...well...when you know what the expected output is.
