Coockie para PhP

[jotaincubus]

setcookie("ya_votaste[1]",$valor1, time()+3600*24);
setcookie("ya_votaste[2]",$valor2, time()+3600*24);
setcookie("ya_votaste[N]",$valorN, time()+3600*24);

Mira este bonito ejemplo que nos regala la pagina oficial de PHP

<?php
// set the cookies
setcookie("cookie[three]", "cookiethree");
setcookie("cookie[two]", "cookietwo");
setcookie("cookie[one]", "cookieone");

// after the page reloads, print them out
if (isset($_COOKIE['cookie'])) {
foreach ($_COOKIE['cookie'] as $name => $value) {
$name = htmlspecialchars($name);
$value = htmlspecialchars($value);
echo "$name : $value <br />\n";
}
}
?>
