检查服务器是否为https不起作用

Question

I'm trying to check if a server has https enabled but it never goes into the if, but in the else statement.

if ($_SERVER['HTTPS'] == "yes") {
    echo "HTTPS";
} else {
     echo "HTTP";
}

what am I doing wrong?

Answer 1

It should read "on", not "yes"

if ($_SERVER['HTTPS'] == "on") {
    echo "HTTPS";
} else {
     echo "HTTP";
}
