你如何设置一个多个值的PHP cookie？

Question

我想创建一个存储用户名和用户ID的php cookie.或者只使用一个来获得另一个更好？

Answer 1

如果您只想存储两个值,可能更容易连接它们并将其存储为:

setcookie("acookie", $username . "," . $userid);

并在以后检索信息,

if(isset($_COOKIE["acookie"])){
    $pieces = explode(",", $_COOKIE["acookie"]);
    $username = $pieces[0];
    $userid = $pieces[1];
}

干杯,

Answer 2

    <?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";
    }
}
?>
