checking for resources in every function

[stijn0713]

i want to determine

 

for every function or class method     in all the core codeigniter functions, libraries and helpers,

 

how many resources (http://php.net/manual/en/language.types.resource.php) these functions or class methods have.

 

Any idea what is a simple way to do it?

 

 

So far, i've

 

- include all the desired files (core, libraries, helpers)

- list down all the user defined classes and their methods and user-defined functions

And how exactly do functions and methods "have resources"?
