Thanks

Here is how I do it:

//set the cookie:
setcookie("Cook ieTest", "t");

//test of the cookie exists (can only be done in the next page / load)
if($_COOKIE["CookieTest "] == "t") {
echo "cookie exists";
}

Thanks it works. However, if the cookie doesn't exist, I get a warning on
the rendered page similar to this one:
Notice: Undefined index: aTestCootie in c:\proyectos\we bsites\test\act ion.php
on line 13

That's great for debugging, but how do Iavoid this from showing up in production
code?

Thanks

if (isset($_COOKIE['CookieTest'] && $_COOKIE['CookieTest'] == 't') ...
