you can try this code
<?php
$count = count($_COOKIE);
$name = "Cookie_".($count+1);
$value = "xxxsss.com";
setcookie($name, $value);
print("<pre>\n");
print("One cookies were added.\n");
print("$count cookies received.\n");
foreach ($_COOKIE as $name => $value) {
print " $name = $value\n";
}
print("</pre>\n");
?>
