php邮件功能发送多封电子邮件

Question

I am trying to implement the simple email function with php mail. Code is as follows

    $headers = 'From: "From Display Name" <[e-mail]>' . PHP_EOL .
       'Cc: "CC Display Name" <[e-mail]>' . PHP_EOL .
       'X-Mailer: PHP-' . phpversion() . PHP_EOL;
   if(mail('[e-mail]', 'test', 'test message', $headers, '[e-mail]')) echo "sent";
   else "not sent";

But problem is this code is sending the same email 6 times, and i can not figureout why... any ideas? The "Sent is echoed only one time though!!!"

Complete CODE:

if($_POST['submitted']=="1"){
$error = "";

if($error==""){

    $headers = 'From: "From Display Name" <[e-mail]>' . PHP_EOL .
       'Cc: "CC Display Name" <[e-mail]>' . PHP_EOL .
       'X-Mailer: PHP-' . phpversion() . PHP_EOL;
   if(mail('[e-mail]', 'test', 'test message', $headers, '[e-mail]')) echo "sent";
   else "not sent";

}

}
