How to find out in php what tests are in the directory?

Question

PHP

I need to get data by pressing a button (on request), or rather an array in which there will be a project, file name, method, etc. All this lies in the tests directory and unit tests are located there, how can this be implemented?

ps: the logic is something like this in the tests folder, it looks for a directory, let's say p1, in this directory it looks for php files, let's say Test.php, in this file there are methods test_foo and others, the
tests array:
p1, Test, foo
p1, Test, foo2
p1, Test2, foo
p2, Test, foo
