Where is there PHP executable in this docker?

[Spec86]

Hello!

I use Ubuntu 20.04.
Install completed. I set PHP 8.1. http://localhost:8000/ in Firefox is work.
I use CodeLite IDE. I run CodeLite - PHP Setting - General - PHP Executable.

1. Where is there PHP executable in this docker for CodeLite IDE?
2. How do I run PHP script in command line in this docker?
