Question

Is there a better way to profile code then:

$start1 = microtime(TRUE);
for($i=0;$i<count($array);$i++)
 {
    //do something
 }
$time1 = microtime(TRUE) - $start1;

Answer 1

Xdebug or Zend Debugger if you have some difficulty to install Xdebug.

Their profiler will time everything for you without any modification of your code.

Answer 2

Without using an external tool, I would say you've done the best you can.

If you want to use a tool built for the purpose, the other answers are dead-on.
