The 'other' guy mentioned that while() is faster than foreach, is this true? I read a few days ago somewhere on php.net that foreach() is the recommended (by php devs) way of iterating over arrays.... also, compare these 2 lines: while (list(, $idcat) = each($idcats)){ /* ... */ } foreach ($idcats as $idcat){ /* ... */ } now its seems to me that the foreach version is 'up' 2 function calls on the while loop, all else being equal the foreach loop has to be faster (given that calling functions is relatively very expensive)... or is foreach() _really_ heavy when compared to while()? not that I care too much, I find foreach() more pleasing to the eye and there is less to type (in the given example). :-) rgds, Jochem

what is the best way to explode then loop this string after its taken apart. output should be something like: $id = 4 $cat = gaming etc.. im just looking for the best/fastest way to do this. the string can grow to 200 or so bytes, maybe more.

200 bytes is chump-change. It really doesn't matter how you do this, within reason.
