如何为PHP邮件添加自定义标头？

Question

I have a mail function with the standard parameters:

mail($to, $subject, $message, $headers);

Where:

$headers = "From: [e-mail]";
$headers .= "
Content-Type: multipart/alternative; boundary=\"PHP-alt-".$random_hash."\""; 

Now, I'm trying to get the sent e-mails to show 'My Site' as the sender instead of '[e-mail]' but if someone responds to the mail it still needs to go to [e-mail].

I've tried putting "My Site" in the "From" field before and after the e-mail address but it just appends to the address. I've tried appending it to the $headers variable but that messes the whole e-mail up. I've also tried adding it this way:

$headers .= "
My Site";

but that doesn't seem to do anything.

I know this can't be complicated as I've seen it done a hundred times, but I can't seem to find a straight-forward answer for this - how do I 'mask' the admin e-mail with the site name but still keep it as the address any response goes to?

Answer 1

Change your From: header to "From: My Site <[e-mail]>"

$headers = "From: My Site <[e-mail]>";
$headers .= "
Content-Type: multipart/alternative; boundary=\"PHP-alt-".$random_hash."\"";

From the PHP Docs.

Answer 2

There is the "From: something <[e-mail]>"; header, and then there is also the optional fifth parameter of mail() which allows you to override the from setting that may or may not be set in php.ini.

<?php
  $to = '[e-mail]';
  $header = 'MIME-Version: 1.0' . "
";
  $header .= 'Content-type: text/html; charset=iso-8859-1' . "
";
  $header .= "From: Name <[e-mail]>" . "
";
  $fifthp = '-f [e-mail]';
  mail($to, $subject, $message, $header,$fifthp);
?>
