PHP install with Apache

I have a problem on installing PHP 5.3.1 with Apache Server 2.2.14. When I 
adding the command "PHPIniDir" into httpd.conf, I cannot start the Apache 
Server anymore. By my observation, It should have some problems when i add 
an extension into the PHP module. I would like to ask how can i fixed it?

#httpd.conf

#BEGIN PHP INSTALLER EDITS - REMOVE ONLY ON UNINSTALL
PHPIniDir "C:/Program Files/PHP/"
LoadModule php5_module "C:/Program Files/PHP/php5apache2_2.dll"
#LoadFile "C:/Program Files/PHP/ext/php_mysql.dll"
#END PHP INSTALLER EDITS - REMOVE ONLY ON UNINSTALL

#php.ini

extension_dir="C:\Program Files\PHP\ext"
