using the __FUNCTION__ and __CLASS__ constants effectively

using the FUNCTION and CLASS constants effectively

goodfella

I've been considering building a debugging/logging framework for complex php applications.

Since debugging PHP appz is really a pain in the ass. I want to do something like this

function debug($msg)
{
  echo __CLASS__."::"__FUNCTION__" ".$msg";
}

and implement this in every function of an framework file.

BUT, the problem is that these constants are related to the executing code, of course, so it gets the function name "debug".

Is there anyway to let this function retrieve the class & function name of the script that executing this function?

I've looked at eval but that didn't worked out.

Any suggestion is very welcome!

Thanx in advance

I'm not sure the PHP language provides that sort of access to the function stack. At least, not without a suitable extension - I found xdebug to be quite useful in a development environment.

thank you for your replay, I've been considering Xdebug for a while but I don't use it. I know it can be usefull thought, but the big downside is that you must have access to the server. So it won't work at public servers.

I'm still asking myself why it can't be done. there must be someway. even if it's a dirty method, i don't care actually. the benefits of this method is so amazingly usefull.

thanx for your reply

Well, you wouldn't install xdebug on the public server, only on your own - it's more a development-only extension. You don't want site visitors being greeted with stack traces and other tidbits of information about the site's internal workings - they don't want to know any of that, and if they do, you probably don't want them to.

yes i understand your point of view. Since I develop on many servers using SSH and VIM, I do need an easy way to see debug information. I use a framework to build my applications on. I hide debug information for visitors though, for real hacks/feature implementation I sometimes don't display any output at all, except to myself of course.
