Hey @dfdrdgdsges as you’ve noted we don’t officially support PHP, but it is installed in the container so you can use it. There are a few examples of other people’s work at https://glitch.com/search?q=php, which I assume you’ve also seen, and there’s one by one of our staff members at https://glitch.com/~php-poc.
If you can give us some more details about what problems you’re running into and your project name we can probably offer some more specific help.
