<?php
   
function emptyInputSignup($name, $email, $username, $pwd, $pwdRepeat) {
    $result;
    
    if (empty($name) || empty($email) || empty($username) || empty($pwd) || empty($pwdRepeat) {
            $result = true;
    } 
    else {
        $result = false;
    }
    return $result;
}
    
function invalidUid($username) {
    $result; 

    if (!preg_match("/^[a-zA-Z0-9]*$/", $username)) {
        $result = true;
    }
    else {
        $result = false; 
    }
