Sending ajax forms to mail, (if there is more than one form) how?

Question

PHP

Guys, hello everyone
Such a question:
I use sending forms via ajax to the mail. Everything sends well.
But there is not one form on the page, but as many as 10 (that is, 10 form tags). I made 10 php files and ajax codes.
Everything works great. But the customer asked for the php file to be one. How do I merge 10 php files into one? (php I don't know, so please help). And most importantly, you need to take into account that the title is different for each form should come.
Thank you all for your help))
ajax code:
$(document).ready(function () {
$("#form2").submit(function () {
$.ajax({
type: "POST"
, url: "mail2. php"
, data: $(this).serialize()
}).done(function () {
$(this).find("input").val("");
$("#form2").trigger("reset");
$.fancybox.open($( "#pop"));
setTimeout(function () {
$.fancybox.close();
}, 1500);
});
return false;
});
});

PHP code:
$recipient = "";
$sitename = "";

$tel = trim($_POST["tel"]);
$message = "Phone: $tel\n";

$pagetitle = "New ticket from the form. Website \"$sitename\"";
mail($recipient, $pagetitle, $message, " Content-type: text/plain; charset=\"utf-8\"\n From: $recipient");

In the "mail.php" form handler, you check what data came from which form, based on the received data, you form the response header. There is nothing complicated in this!
