This is expected. debug_backtrace() shows the stack from the current 
point. Since the email_save_log_03 function has already ended at the 
point debug_backtrace() was called, it has left the stack and is not shown.

The function would only be mentioned if debug_backtrace() was called 
from inside the function (including another function called by the 
function in question).

Methods I would use to find where the function is defined:

* Open the project in a PHP-capable IDE such as PHPStorm. You can then 
ctrl-click (or equivalent for the IDE in question) the function call to 
go to where it's defined.

* On the linux command line: grep -irn 'function.*email_save_log' *

(.* is used here to handle any amount of unknown whitespace such as 
tabs, spaces, etc)

Another method you could try to find the function is to use Reflection.
