Reflection API idea View as Markdown

Whoops, that memcmp should be a strcmp.

Subject: [PHP-DEV] Reflection API idea

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.

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)
