I don't see a function call for check(). It's either not working because you didn't call the function or there is more code you haven't shared which contains the actual problem.

What was stated above is correct, you aren't calling your check function in your code, you need:

<?php
function hello() {
    echo "hello,world!";
}

hello();

$current_user = "Vidit";

function check() {
    global $current_user;
    if($current_user=="Vidit") {
        echo "Hey! This is Vidit";
    } else {
        echo "Sorry!";
    }
}

check();
?>

With that in place you will see "hello,world!Hey! This is Vidit" on your screen.
