Update information Edit(Aug.3)
At Jun-05 22:49:25UTC, they released PHP5.4.16. So, I downloaded a Thread Safe version php-5.4.16-Win32-VC9-x86.zip for my server (WindowsXP SP3 (x86)).
Acoording to the ChangeLog, it has some bug fixes, also patches for CVE-2013-2110.
As php5apache2_4.dll included in the official PHP binary 5.4.10+, I extracted the zip archive and replaced all PHP5.4.15 files with all PHP5.4.16 files except my php.ini. Then, I restarted my Apache. That’s it.
If you need how to configure PHP5.4, please see the post on my Japanese blog. Of course, it is only in Japanese and for a mbstrings user, but I think the information gives some help for you.
I’ve also updated to phpMyAdmin4.0.3.
If you need how to configure PHP5.5, please see “To create a Wamp-like Web Server in Windows7-#2“.
