Here's an idea for the maintainer of the Reflection API, to be able to view
the class a method is defined in (if not overridden).


class Vehicle {
    function go() {}
    function crash() {}
}

class Car extends Vehicle {
    function crash() {}
    function collectInsurance() {}
}

class Ford extends Car {
    function fixOrRepairDaily() {}
}

Reflection::export(new ReflectionClass(Car));


Class [ <user> class Ford extends Car ] {
  
  - Methods [4] {
    Method [ <user> public method fixOrRepairDaily ] {
    }

    Method [ <user> public method crash inherited from Car ] {
    }

    Method [ <user> public method collectInsurance inherited from Car ] {
    }

    Method [ <user> public method go inherited from Vehicle ] {
    }
  }

I am developing on a Windows machine so a Unified Patch isn't easily
attainable (with the tools I have at least).

Psuedo Patch:
Modify _function_string in zend_reflection_api.c to take a zend_class_entry
of the reflecting class or `NULL` if not used in a class context.
Then add the "inherited from" section as below (or however you'd like to
implement).

string_printf(str, "%s", fptr->common.function_name);
if (fptr->common.scope && memcmp(fptr->common.scope->name, ce->name)) {
    string_printf(str, " inherited from %s", fptr->common.scope->name);
}
string_printf(str, " ] {\n");


Not sure if this works in all situations, I'll leave that for you guys to
determine if you think this is useful functionality.

Whoops, that memcmp should be a strcmp.

Hello Bob,

  have you looked at head output of Reflection lately? I guess that contains
all you want, right?

Hi,
	This has been do-able in PHP5 for somewhile, (wrote a reflection browser while ago to show such things)

Hello Jared,

  hey cool stuff! Any chance you could publish this or make it a PEAR class
or put it into the newly created Reflection extension as example?
