Quick PHP Cookies question

First of all, a minor point, in that your variable $myVal need not be in quotes:
[PHP]<?php
setCookie("real.com", $myVal, time() + 3600 * 24);
?> [/PHP]
Think of your cookie as an array and the above has just set the value $myVal to the array key "real.com". On your second and subsequent scripts you can then output the cookie:
[PHP]<?php
echo $_COOKIE["real.com"];
?> [/PHP]
Other tricks you can try with arrays include checking if a cookie variable has been set:
[PHP]<?php
if (isset($_COOKIE["real.com"])) {
echo "real.com is set";
} else {
echo "real.com is not set";
}
?> [/PHP]
And listing out all the cookie variables currently set (remember it is an array):
[PHP]<?php
foreach($_COOKIE as $key => $value) {
echo $key." : ".$value;
}
?> [/PHP]
