PHP Question

PHP library to generate EML email files?

I'm trying to generate EML files from PHP. Is there any library that will allow me to easily create them? I could find some ActiveX component on the internet but would rather use something more portable.

Answer Source

I ended up building the MIME message myself using this kind of template, where each field is replaced by a TEMPLATE_<name> variable:

MIME-Version: 1.0
Content-Type: multipart/mixed; boundary="080107000800000609090108"

This is a message with multiple parts in MIME format.
Content-Type: text/plain

Content-Type: application/octet-stream;name="TEMPLATE_ATTACH_FILENAME"
Content-Transfer-Encoding: base64
Content-Disposition: attachment;filename="TEMPLATE_ATTACH_FILENAME"


Then creating the final message is quite simple using str_replace:

$content = file_get_contents("Template.eml");
$content = str_replace("TEMPLATE_FROM_ADDRESS", $fromEmail, $content);
$content = str_replace("TEMPLATE_TO_ADDRESS", $toEmail, $content);
// etc. for each template parameter
// Also don't forget to base64_encode the attachment content;
$content = str_replace("TEMPLATE_ATTACH_CONTENT", base64_encode($attachContent), $content);
