$array = debug_backtrace();
        echo(str_replace(ROOT, "", $array[0]['file'])." (line ".$array[0]['line'].")");
   

     echo "<pre>";
        print_r($var);
        echo "</pre>";
    }
}
    1. function pr($var) {
    2. if (DEBUG > 0) {
    4. $array = debug_backtrace();
    5. echo(str_replace(ROOT, "", $array[0]['file'])." (line ".$array[0]['line'].")");
    7. echo "<pre>";
    8. print_r($var);
    9. echo "</pre>";
    10. }
    11. }
    12.  

    With this minor change, you can see where your debug calls are...
