mysql PHP登录系统接受Unity发送的任何密码

I'm creating a login system in Unity, and it works to login with a username from the database, but the login is successful no matter what I type into the password field. I don't understand why, as I thought this code would check whether the password match with the username or not. Any clues? I'm btw very new to PHP. Thanks :)

php code:

$check = mysql_query("SELECT * FROM unitytut WHERE `user`='$user'");
$numrows = mysql_num_rows($check);

while($row = mysql_fetch_assoc($check)){
if($pass = $row['pass']){
    die("login-SUCCESS");
    }
    }

unity code:

    WWWForm form = new WWWForm ();
        form.AddField ("user", user);
        form.AddField ("pass", pass);
        WWW w = new WWW ("http://mywebpage.dx.am/Login.php", form);
            StartCoroutine (Login (w));


   IEnumerator Login(WWW w){
        yield return w;
        if (w.error == null) {
            if(w.text == "login-SUCCESS"){
       Debug.Log("LOGIN SUCCESS");
    }
    }

    Well here is your problem, you're using a single =, because of this $pass is being set, which will return true, use a double == instead, as this is for checking if its equal to.

    So this:

    if($pass = $row['pass']){
        die("login-SUCCESS");
    }
    

    Should be this:

    if($pass == $row['pass']){
        die("login-SUCCESS");
    }
    


    Also, mysql_* functions are deprecated, you might want to look into PDO or MySQLi prepared statements.
