PHP 5.4.5 and 5.3.15 were released on July 19, 2012 and below are the 64 bit builds for Windows. A number of security issues and bugs have been fixed since the release of PHP 5.4.3 and 5.3.13 and as such you should upgrade to PHP 5.4.5 or 5.3.15 as soon as possible. The complete official changelog can be found here.
As usual, the following builds were compiled with Visual C++ 2008 (VC9) and should work with the 64 bit builds of Apache HTTP server available on my site. I did not have time to test the 5.3.15 builds so let me know if you have any issues.
PHP 5.4.5 (Thread Safe)
PHP 5.4.5 (Non Thread Safe)
PHP 5.3.15 (Thread Safe)
PHP 5.3.15 (Non Thread Safe)
