PHP Send HTML Email
This easy to use function will allow you to send multipart/html email from your website.
The "multipart" means you can send both a html and a text version of your message, the receiver will see one of the versions depending on the program/application used to read the email.
When calling the function you define:
- receiver name/email
- email subject
- plain text version of the email
- html version of the email
- sender name/email
<?php
if(!function_exists("tnt_multipart_mail")){
function tnt_multipart_mail($email_receiver, $email_subject, $email_text, $email_html, $email_from){
// bountry is a string that will delimit the text from html version of the message
$email_boundary = uniqid('', true);
// set the return (Bounce) address
$return_path = $email_from;
// if sender is formatted as "Name <user@site.com>" then take sender from inside the <> (last occurance)
if(preg_match('/<([^<]*)>$/', $email_from, $receiver_matches)){
$return_path = $receiver_matches[1];
}
// note that ORDER is important, e.g. content-type AFTER mime (says SpamAssassin score)
$email_headers = "From: ".$email_from."\n";
$email_headers .= "MIME-Version: 1.0\n";
$email_headers .= "Content-Type: multipart/alternative;\n";
$email_headers .= " boundary=\"$email_boundary\"\n";
// start building the text AND html parts of the message body
$email_message = "";
$email_message .= "--$email_boundary\n";
$email_message .= "Content-Type: text/plain; charset=UTF-8\n";
$email_message .= "\n";
$email_message .= $email_text."\n";

}
}
// replace "receiver@example.com" with the name of your receiver
// replace "Sender Name <sender@example.com>" with your name and email, you can also just use email without name
// replace the content of the plain text and html part of the email
tnt_multipart_mail("receiver@example.com", "testing html email", "hello (this is plain text)", "<strong>Hello (this is html)</strong>", "Sender Name <sender@example.com>");
