because your variable is set already! try doing this:
echo empty($asdadadadadadasd); you will get a warning and have a FALSE value. Elias "Verdana Musone" <[EMAIL PROTECTED]> wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... I always set error_reporting(E_ALL) oR error_reporting(2047), but i have never got any errors when just use empty() to determine whether a variable is set. If the variable is: 0, null, not set or an empty string. Then the empty() will return true. It's unnecessary to call isset() first. ----- Original Message ----- From: lallous Sent: 2002Äê8ÔÂ3ÈÕ 15:01 To: [EMAIL PROTECTED] Subject: Re: [PHP] isset($var) && !empty($var) same time! Just use empty() ?! With error_reporting(E_ALL) you'll get a bunch of warnings if you only use empty() w/o the isset() ! use isset() first and then check wheter empty or not empty! so there is not one function that tests for empty and isset same time!?
