Question

I am unable to read the cookie using $_COOKIE['mycookie']. I am using PHP-Apache on Linux box. Is there any seeting in php.ini or httpd.conf to activate cookie.

Did you set the cookie properly?

<?php
$value = 'something from somewhere';

setcookie("TestCookie", $value);
setcookie("TestCookie", $value, time()+3600);  /* expire in 1 hour */
setcookie("TestCookie", $value, time()+3600, "/~rasmus/", ".example.com", 1);
?>   
<?php
// Print an individual cookie
echo $_COOKIE["TestCookie"];
echo $HTTP_COOKIE_VARS["TestCookie"];

// Another way to debug/test is to view all cookies
print_r($_COOKIE);
?>
