Hello Reader's! if you want to get the name of function and method being called, Then by using PHP you can do this as explain below:-
Lets's see the example as below here we are using the info provided by a php exception, it's an elegant solution:

function GetCallingMethodName(){
  $e = new Exception();
  $trace = $e->getTrace();
  //position 0 would be the line that called this function so we ignore it
  $last_call = $trace[1];
  print_r($_call);
}

function firstCall($a, $b){
  theCall($a, $b);
}

function theCall($a, $b){
  GetCallingMethodName();
}

firstCall('lucia', 'php');

And the output will be as is:-

Array
(
  [file] => /home/lufigueroa/Desktop/test.php
  [line] => 12
  [function] => theCall
  [args] => Array
    (
      [0] => lucia
      [1] => php
    )

)

In the array key 'function' will tell the function and in the key 'args' will tell the number of args or param being passed to this function.
