How to test if cookie is already set?

I have a page that when the user logged in, I set the cookie. However, I couldn't figure out how to test if the cookie is already set. If the cookie is alredy set for that user, then do not set the cookie again.

Any suggestion is much appreciated.

Code: Select all

if(!isset($_COOKIE)){
      set_cookie();
   }

Thank you very much...I'll give that a try. I thought it would be something harder.

Oh, by the way, one more question. Is the $_COOKIE something I manually have to declared or is that part of the PHP reserved word to test if cookie is set?

Code: Select all

<?php
print "<pre>"; 
print_r($_COOKIE); 
print "</pre>"; 

?>
see all the cookie values that are stored
