How to turn an 'array-esque' variable (3,6,2,5) into a functional array?

[mitwess]

I have a variable from hidden post form ($nums) which already resembles an array (2,6,2,5,etc.) but array($nums) is giving me an error.  so what's the best way to make $nums an actual functional array?

explode

i figured that out.  but how do i get it back into an array.  $nums gets one number larger each time my script loads, so i'm not dealing with a static set of numbers (i.e. array($nums[0], $nums[1], nums[2]).  how do i rearray an incrementally growing $nums?

Could you paste some of oyur code, because I don't quite understand the issue...
