EDIT: PHP<5.3, Windows

Try using a profiler. ( http://xdebug.org/docs/profiler )

Measuring code cycles may vary because the zend engine may or may not optimized the opcodes, the way the zend engine was compiled may lead to it doing some operations faster, etc.

Also, the time it takes to connect to the DB may be "handled" by doing some mock classes (http://en.wikipedia.org/wiki/Mock_object), but in a real application, the time it takes to connect to the DB is important, because the user perceives the whole webpage as being slow, not the SQL server being slow:)
