Not sure why it does it, but doesn't seem to be a huge deal. I'm guessing it's because an empty string is still a string. It's not null. Anyway, it's documented at: http://us3.php.net/manual/en/function.explode.php A user writes: "If you split an empty string, you get back a one-element array with 0 as the key and an empty string for the value." -TG = = = Original message = = = I'm wondering why this is. $data = ""; $array = explode(",",$data); $count = count($array); $count will = 1 $data = "Test"; $array = explode(",",$data); $count = count($array); $count will = 1 $data = "Test,Test"; $array = explode(",",$data); $count = count($array); $count will = 2 Why doesn't the first one give me an answer of 0 instead of 1. I know I could do a IF $data == "[empty]" and then not count if its empty and just set it to 0, but am wondering if there was a better way. -- Kevin Murphy Webmaster: Information and Marketing Services Western Nevada Community College www.wncc.edu 775-445-3326 ___________________________________________________________ Sent by ePrompter, the premier email notification software.
