PHP mail Function With Attachments

This code sends an html formatted email with attachments. This email sending script actually sends both a plaintext and an html body of the email, allowing the email client to choose which to display. The plaintext email is generated by stripping html tags from the html formatted body, and replacing
with newline characters.

One of the nice things about this script is that the attachments are stored in an array. If you want to add another attachment, all you have to do is copy and past an existing line in the attachment array, and change the filename.
For each attachment, it automatically looks up the corresponding mimetype.

This helped me a lot! Thank you!

Rick Torzynski on 2010-04-17 20:52:32

Thanks! The ONLY place that presented a simple and complete example.

icebox on 2010-07-20 11:12:17

Hey, thanks, works great, just one thing. In your example you define $subject, but then call $subj.

Deepak on 2010-07-25 18:30:39

Thx you very much from bottem of my heart really this is really a good script God Bless You

Steve on 2011-05-12 03:39:11

Very nice of you to offer, and thank you.
This was my last attempt to solve an error, but I still get a failure with an attachment > 750KB. Have adjusted all php.ini memory limits up to 20M to no effect.
Since it's obvious that you are expert in this arena, do you have any clues ?
Thanks again for your fine routine.

ATR on 2011-07-16 16:00:38

Thanks for providing a readily re-usable function! Tired of finding scripts that require modification...

subu on 2013-05-11 04:50:29

Awesome. the clarity in the example and the way it is written...and shared on the site...its greate.. Seen many sites with suggestion in parts... but the detailing, comments naming ..everything is great...thanks once again....
