检查会话 - php不打印[关闭]

Question

<?php session_start();
$_SESSION['loggedIn'] = "no";
echo "Logged In: ". $_SESSION['loggedIn'];

if($_SESSION['loggedIn']=="yes"): 
    echo "logged in";
}
else{
    echo "not logged in";
}
?>

I am simply trying to check if the session "loggedIn" is yes or no, but the program doesn't print anything.

Why does it not print anything?

You are using alternative if/then as well as regular syntax.

if($_SESSION['loggedIn']=="yes"):

should be

if($_SESSION['loggedIn']=="yes"){
    echo "logged in";
}
else{
    echo "not logged in";
}

its a simple syntax error
