php email sending errors

Question

Fairly new to PHP, and I'm working on a simple form,

Users enter in their information and then once it's checked to see if the information is there and not empty, then use the mail function to send it out

here is the code

I get the error

Parse error: syntax error, unexpected ',' in C:\xampp\htdocs\registration.php on line 20

line 20 is where the mail function is

if (isset ($_POST['attendee']) && isset ($_POST['attending']) && isset ($_POST['message']) && isset ($_POST['contact_email']))
{

    $attendee = $_POST['attendee'];
    $attending = $_POST['attending'];
    $contact_email = $_POST['contact_email'];
    $message = $_POST['message'];

    if(!empty($attendee) && !empty($attending) && !empty($message) && !empty ($contact_email))
        {
            $to = 'someemail@gmail.com';
            $subject = 'Wedding Information Received'.'attending';
            $body = $message;
            $headers = 'From: '.'contact_email';

            if (@mail(($to,$subject, $body, $headers))){
                echo 'Thanks for Reserving';
            } else{
                echo 'Sorry, an error occured. Please Try again     later.';
            }
        }
    else{
        echo ' All Fields are Required';
    }
}   

Answer 1

You are using 2 (( in front of mail instead ( and 3 ))) instead of 2 )) at the end ...

Replace

  if (@mail(($to,$subject, $body, $headers))){

With

  if (@mail($to,$subject, $body, $headers)){
