致命错误:函数名必须是.. PHP错误中的字符串

Question

嗨,我有一个名为User的类和一个名为insertUser()的方法.

function insertUser($first_name, $last_name, $user_name, $password, $email_address, $group_house_id)
  {
    $first_name = mysql_real_escape_string($first_name);
    $last_name = mysql_real_escape_string($last_name);
    $user_name = mysql_real_escape_string($user_name);
    $password = mysql_real_escape_string($password);
    $email_address = mysql_real_escape_string($email_address);

    $query = "INSERT INTO Users
              (FirstName,LastName,UserName,Password,EmailAddress, GroupHouseID) VALUES
              ('$first_name','$last_name','$user_name','$password','$email_address','$group_house_id')";
    $mysql_query($query);
  }

我称之为:

$newUser = new User();
$newUser->insertUser($first_name, $last_name, $user_name, $email, $password,          $group_house_id);

当我运行代码时,我收到此错误:

Fatal error: Function name must be a string in /Library/WebServer/Documents/ORIOnline/includes/class_lib.php on line 33

有人知道我在做什么吗？此外,这是我第一次尝试使用OO PHP.

干杯,

Jonesy

$mysql_query($query);=> mysql_query($query);.请注意丢失的美元.如果您尝试对变量使用函数调用语法,它将查找具有由变量值指定的名称的函数.在这种情况下,你没有mysql_query变量,所以它没有任何东西,这不是一个字符串,因此给你错误.
