php setcookie 全局,PHP

我进行了登录，设置了一个带有估算电子邮件地址值的cookie，因此在global.php文件中，它使用以下命令存储用户数据数组：

$email = $_COOKIE["PeopleHub"];

$getuserdata = mysqli_query($con, "SELECT * FROM Earth WHERE email='$email'");

$userdata = mysqli_fetch_array($getuserdata, MYSQLI_ASSOC);

Cookie尚未设置，我知道这一点，因为我做了一个测试文件：

echo $_COOKIE["PeopleHub"];

它只是做了一个空白页。

登录代码(设置cookie的位置)：

include "global.php";

?>

Login

echo "We currently have " . $usercount . " members, " . $onlinecount . " of which are online. ";

?>

if(isset($_POST["email"])){

$email = $_POST["email"];

$password = sha1($_POST["password"]);

$check = mysqli_query($con, "SELECT * FROM Earth WHERE `email`='$email' AND `password`='$password'");

$check = mysqli_num_rows($check);

if($check == 1){

setcookie("PeopleHub", $email, 0, '/');

echo "We logged you in!";

}

else {

echo "We couldn't log you in!";

}

}

?>
