Using PHP4 Beta 3 :
calling my website index.ihtml with the following code:
<? php
     if ($action == "")
     { do_something(); }
?>

PHP4 Beta 3 now complains "undefined variable action", but with PHP3 and PHP4 Beta 2
everything worked fine !!!
Now i have to do redirects to my file wih index.ihtml?action=  do get it to work ..

ist not a bug, its a feature :)

either adjust the warning level in php.ini

or test with isset() instead of ==""
