Get all Functions Names of All CONTROLLERS

@kilishan

But PHP will parse all the controller files then. What do you think about scanning the sources with a regular expression?

That's true, it will parse them all, but I'm pretty sure that it, being a native method written in C, is likely to have better performance than a regular expression. While I think either way could work, I think the performance difference would be negligible between the two. And, since I don't know what the purpose is, I would personally go with the easier solution. Then, if performance was found to be an issue down the road, I would simply cache the results.
