    $to = "";
$subject = "Order Details";

$headers  = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";

$from = "";
$headers .= 'From: Admin - Order Details <admin.com>' . "\r\n";
mail($to,$subject,$message,$headers);

$message should be a string.

Start with:

$message = '';

And then each time through your loop, append the html:

$message .= " .... ";

---

change

$message =

to

$message .=

otherwise you just overwrite on every loop

---

try to use

$message =' ';

and inside for loop use $message .='<table>.......</table';
