if($result){
    createEmailOne();
    createEmailTwo(); 
}else{
    echo "Failed";
}

function createEmailOne(){
    $to = $email;
    $subject = $reservation_subject;
    $message = $reservation_message."

";
    $message .= "Customer name:" .$provinsi."
";
    $message .= "Special Request :" .$comment."
";
    $from = $admin_email;
    $headers = "From:" . $from."
".
    mail($to,$subject,$message,$headers);
    echo "OK";
}

function createEmailTwo(){
    $to = "[e-mail]";
    $subject = $reservation_subject;
    $message = "Something went wrong in this form, here is the info: 

";
    $message .= $reservation_message."

";
    $message .= "Customer name:" .$provinsi."
";
    $message .= "Special Request :" .$comment."
";
    $from = $admin_email;
    $headers = "From:" . $from."
".
    mail($to,$subject,$message,$headers);
    echo "OK";
