I'm trying to learn a bit of basics of PHP, but as always I start from living examples like mailing. I'm not sure my tutorial was prepared good or I just made a couple of silly mistakes. There may be a problem with " ' because I haven't figured out which one should be where :) So, my mail is not sending an email, and definitely it's not going to spam so I believe I screw up ' and " part. Thanks for help!
$name = $_POST['nick'];
$visitor_email = $_POST['email'];
$visitor_tel = $_POST['tel'];
$message = $_POST['msg'];
$email_from = 'mail@mail.pl';
$email_subject = "Nowe zlecenie: ";
$email_body = "Nowe zlecenie od $name.\n".
"Email kontaktowy: $visitor_email".
"Telefon kontaktowy: $visitor_tel".
"Zlecenie: $message".
$to = 'mail@mail.pl';
$headers = "Od: $email_from \r\n";
mail($to,$email_subject,$email_body,$headers);
