PHP 5.3 Installation
Windows PHP distributions are now available from http://windows.php.net/download/. Installing PHP as an Apache 2.2 module using the Apache Lounge build, so you should download the VC9 x86 Thread Safe Zip file.
Download the VC6 builds if you are using the standard Apache.org web server. The VC9 builds should be used for the Apache Lounge binaries or IIS.
A Thread Safe version should be used if you install PHP as an Apache module. The Non Thread Safe version should be used if you install PHP as a CGI binary.
You can now follow the instructions at How to Install PHP on Windows from step 2 onwards. Note that, in step 3, php.ini-recommended is now named php.ini-development; you still need make a copy and rename it php.ini.
If you have previously defined a working PHP configuration file, a tool such as WinMerge can help you compare and copy existing values to your new php.ini file.
PHP 5.3 Zend Extension Installation
When I install ZendGuardLoader for php 5.3 on Windows, I found that zend_extension can only workred in VC9 version and must be used as CGI/FastCGI for Apache2.
If successful installed , you will see the following info of phpinfo() output:
This program makes use of the Zend Scripting Language Engine:

Here is my php.ini config:
