Detailed solution

Connecting to their website, we can see this website is running PHP Version 7.4.3.

Furthermore, it is commented at the top that “Flag is inside ./flag.php”

When we try to navigate to /flag.php, we just see “No flag for you!”

If we inspect the source of this page (CTRL+U), we are greeted with the flag.

This was the easy version of phpfuck_fixed.
