Dear all,

   I'm new to the concept of reflection. I have read into the concept but I'm not sure why it should be used apart from documenting the code.

   Invoking a method of a certain class via PHP ReflectionClass is more complicated than simply invoking the method by instantiating the class itself. So, why is ReflectionClass necessary?

   I understand that reflection can avoid hardcoding. Could you offer some examples of using the PHP ReflectionClass which makes coding more efficient?

Regards,
Ming

It is used in metaprogramming, i.e. when "programming the program".

You can find some examples of the usage here:

Dear cxr,

   Thanks for your message. I had read briefly the articles in the sources you offered while I was writing my question, though. May I clarify my question a bit? I'd like to know how PHP ReflectionClass helps in, say, a single webpage in which rows of a database are selected or updated.

Regards,
Ming

I can't imagine how ReflectionClass would be helpfull in that scenario. I'm not saying it can not be helpfull, I just can't imagine how. :)
