Apache could not be started after replacing PHP 5.3.5 to PHP 5.3.8

I’m new to XAMPP and I’d like to learn about it, some trial and error I guess. After I installed XAMPP version 1.7.4 which is using PHP 5.3.5, I need to upgrade the PHP version to the latest.
I downloaded newest PHP version (5.3.8) and then I replace the folder “C:xamppphp” with my new PHP version. But guess what, everything is not running well. I manage to shutdown my Apache service. But I could not start it again. I’ve tried start the apache service using XAMPP Control Panel and Services under Computer Management. Please take a look at the picture below.
It give some message like this “Windows could not start the Apache2.2 on Local Computer. For more information, review the System Event Log. If this is a non-Microsoft service, contact the service vendor, and refer to service-specific error code 1.”
