A php imap script to download gmail attachments

This is a simple php script to automatically download gmail attachments based on incoming author and subject text of email into folder script is run on, but other imap search queries could be used. I use it locally on my linux box in the form of ‘php download-directly-from-gmail.php’ I hope it helps someone.

eg.

orion@orion-Dimension-2350 ~/Downloads/SHUTTERSTOCK IMAGES $ php download-directly-from-gmail.php
