php - Using backtrace_debug to determine caller class and caller method for the function. Am I doing it wrong? -

i have parent class , children class. in parent class define function f() , want print in name of children class extended parent class , name of children method called function. that.

abstract class parentclass {    public function f() {        $backtrace = debug_backtrace();              echo "class: " . $backtrace[1]['class']) . "\n";        echo "function: " . $backtrace[1]['function'];   }  }  class childrenclass extends parentclass {     public function some_func() {         $this->f();    } }   $o = new childrenclass; $o->some_func(); 

and correctly outputs me:

class: childrenclass function: some_func 

the question is: solution appropriate or there better way achieve this? tried use __class__ , __function__ gives me classname , function name of parent class.

if print out $backtrace var might see goes more classes

echo "debug:<pre>".print_r($backtrace,true)."</pre><br />"; 

so calling

$backtrace[1]['class']  

will work might make dynamic. like:

// loop, pseudo-code  $i = 0; $backtrace[$i]['class'] $i++;
