PHP method to get the class name and all function names:

__LINE__ : The current line number in the file.

__FILE__: The full path and file name of the file.

If used in an include file, returns the include file name. As of PHP 4.0.2, __FILE__ always contains an absolute path, while versions before that sometimes contained a relative path.

__FUNCTION__ : Function name (newly added in PHP 4.3.0).
