If you don’t have a debugger setup or would rather just see this sort of information in a log format use this snippet to find where a method is being called from. Note, if you have NetBeans configured with XDebug you can add a break point and watch the callstack for this sort of information.

$trace = debug_backtrace();
//$cache = "$key ".json_encode($value)." $duration";
$cache = '';
$caller = $trace[1]['file'].':'.$trace[1]['line'].' '.$cache;
error_log(__METHOD__.': '.$caller);

The output will go to where you apache error log is, typically /var/log/apache2/error.log:
