如果查询结果为= 1,我应该更换“代码验证？”
我尝试了很多使用num_rows的方法,但它不起作用.
我的 PHP代码：

$con=MysqLi_connect("localhost","mbrconsu_un394x","y1cz9,rd+hf6","mbrconsu_mmx");

    if (MysqLi_connect_errno($con))
    {
        echo "Failed to connect to MysqL: " . MysqLi_connect_error();
    }

    $usuario = $con->real_escaPE_string($_GET['usuario']);
    $senha = $con->real_escape_string($_GET['senha']);

        $query = MysqLi_query($con,"SELECT * From 'login' WHERE usuario = '$usuario' AND senha='$senha'");

        if(CODE TO VERIFY IF QUERY RESULT ROW IS = 1){
            while($row = MysqLi_fetch_assoc($query)){
                $db_username = $row['usuario'];
                $db_password = $row['senha'];
            }
            if($usuario == $db_username && $senha == $db_password){
                return true;
            }
            } else {
            return false;
        }

    MysqLi_close($con);
?>

$query->num_rows;

MysqLi_num_rows($query);
