How to get name of caller function

[Anon]

I would like to know if it is possible inside of a function to get a name of function that called this function.
Example:

function a()
{
b();
}

function b()
{
echo get_caller_function();
// it should print \"a\"
}

Is it possible to implement get_caller_function() and how?

Thnx

more importantly, why? what do you need this for?

[Anon]

Calling a function into a function is possible:

function un(){
print "1 et "; deux();
}
function deux(){
print "2";
}
un();

Is it the answer you want?

[Anon]

No, what uros would be wanting in that case is something that can go inside deux() that would return "un".

Why i need this?

I have some function showErrorMsg, and now i that function i want to know what other function call this error msg so i don't need to call that showErrorMsg with argument of function that generate the error.

I know that i can use LINE FILE but i want to have name of function.

Like in class there is such function where you could get name of calling methind.

Any sugestions?

Such a thing does not exist for functions.

But you don't really want to use that for public-error reports, only for internal logging. The end-user should only see 'an errror occured while doing this' they don't need (nor want) to see function names.

I do need this for internal logging. I'm not dumb to show to public users. But it helps a lot if I see from where error was called.

Maybe any other sugestions how to solve this

The simplest solution is to add the function-name to the error message when you call the function. A bit more work, but it works.
