I can't delete cookie with PHP

I can't delete a cookie with my php code. When I press logout the page refreshes but the cookie is still there.

<?php
if (isset($_COOKIE["admin_login"])) {
    echo "Cookie: ".$_COOKIE["admin_login"]."<br>";
}
if (isset($_GET["logout"])) {
    setcookie("admin_login", "", time()-3600);
    unset($_COOKIE['admin_login']);

}
?>
<html>
<body>
    <a href="?logout">Logout</a>
</body>
</html>

Thank you for your answers. After finding no solution i tried to switch to SESSION.

After some research i made it works great. Thank you all for helping me.

If someone is interested, here is my final code.

<?php
session_start();
if (isset($_GET["logout"])) {
    session_unset(); 
    session_destroy(); 
    header("Location: ../login.php");    
}
if (isset($_SESSION["admin_login_session"])) {
    echo "Cookie: ".$_SESSION["admin_login_session"]."<br>";
} else {
    header("Location: ../login.php");
}

?>
<html>
<body>
    <a href="?logout">Logout</a>
</body>
</html>

This is likely happening because you're outputting data before setting cookie.

setcookie() defines a cookie to be sent along with the rest of the HTTP headers. Like other headers, cookies must be sent before any output from your script (this is a protocol restriction).

if (isset($_COOKIE["admin_login"]))
    anything_that_doesnt_output_text(); // text was causing problem most likely.

if (isset($_GET["logout"]))
    setcookie("admin_login", "", time()-3600); // also, no unsetting
