During development of common library for WordPress plugins and themes ( WordPress development helper library ), I just want to find from which plugin it is called ( I just want to debug the code, but I used in many plugins and i am not able to track from which plugin it is actually loading ).
Then I found about ReflectionClass, reports information about a class.
You can read more detail about ReflectionClass from php.net.
Here is how to get file path from class name
$autoloader_reflector = new ReflectionClass("RT_WP_Autoload"); $class_file_nanme = $autoloader_reflector->getFileName(); echo dirname($class_file_nanme);
This is same as reflection api in java, There are some good reflection examples to get you started reflection api in java at http://docs.oracle.com/javase/tutorial/reflect/index.html
