(I thought >they were the same.) Using a comma is just like using another echo command. So for the above, you're effectively saying: echo "<pre>"; echo print_r($chk); echo "</pre>"; Note that print_r() will (by default) return a 1 (TRUE) upon success, so you end up with a "1" being printed at the end of your data. You could also use this method: echo "<pre>".print_r($chk,TRUE)."</pre>"; The TRUE causes the output of print_r() to be returned instead of printed automatically. The benefit to this method is that you don't end up with the "1" being printed. ---John Holmes...
