I would love to be able, from within a function, to find out the file/line no that called me.

For example:

/// some code ///
$x = call_a_function();


function call_a_function() {

    echo "MY LOCATION: __FILE__ : __LINE__";

    /*** This is what I would LOVE ***/
    echo "CALLED FROM: __CALLING_FILE__ : __CALLING_LINE__";
}

That would be fantastic!

On the Hungarian PHP list this is frequent question, and surely most of the developers -including me :)- would love it too!

Naturally it is another self-administering task to the interpreter, so I would suggest to make it an optional 'developement-time' feature.

Aabout nested includes: it would be good to return a complex data structure, when the programmer can step-back the calling process.

80% done with this. Just need some more testing.
