Hello, Well I am making a script in php and I added

 function redirect($url)
  { 
   header ("location: $url");
   exit;
  }

Ok, well works great, except if it gets called 2 times, on the same page...then errors take over...so How do I make it so it determines wether or not the function exists?

I believe you asked your question wrong. The last 2 words of your question could be the answer: http://php.net/manua...tion-exists.php

But since i assume you want to know whether or not the function has been called. You could try a static variable (i haven't done much work with these, but you could give it a try.

function redirect($url){
   static $called=0;
   if(empty($called){
	  header ("location: $url");
	  $called = 1;
   }
}

But i doubt that's your problem. Headers, unlike php/html, tend to be case-sensitive (mostly for cross-browser compatiblity). http://php.net/manua...tion.header.php

So what you'd want to use is this:

function redirect($url){
   header ("Location: $url");
}

exit() is not needed since that should redirect you the second it's called.
