Re: source of global variable

I think I did misunderstand -- php is not like C where you declare things global both in the main program and in subroutines. If you are not in a function everything is automatically "global"; in php functions you need to declare variables to be global. --so you don't need it the problem looks like the call to strtotime('now') see http://www.php.net/manual/en/function.strtotime.php for the proper usage
