Hi All,

I have a php script that will an catch email passed to it and process it.

#!/usr/local/bin/php -q
<?php
while (!feof(STDIN)) {$s .= fgets(STDIN);}
// Now do some work on the email source in $s.
?>

This works fine. My question is how to save an attachment into the file system from the source. For example, if I isolate the section below, how do I need to process it before saving it into a gif file to create a valid gif?

I assume I need to change the encoding, or otherwise process it, but does anyone know exactly?

Thanks!

Mailparse

Ignacio Vazquez-Abrams
+1 This is most certainly the most efficient solution, though it may not be executable in a shared host.
Artefacto
Check out http://code.google.com/p/php-mime-mail-parser/ for some help, since the Mailparse documentation is non-existent.

For a PHP solution (no C extensions required), there's PEAR Mail_mimedecode.

After parsing the e-mail, you already have the attachment bytestream, no need to base64 decode yourself.

Artefacto
+1  A: 

Try the PEAR_Mail_MimeDecode class from Pear. You can feed it the entire mail, and get back the various MIME chunks... and no need to install an extension.
