The php version 4.4.9 is shipped with the PPCPW version 10.3.2. However php will not be updated automatically during update of PPCPW 10.3.2. To update your php to 4.4.9 please follow the following steps:
1. Download PHP 4.4.9 bundle file from http://www.php.net/get/php-4.4.9-Win32.zip/from/a/mirror
2. Extract the bundle to %SystemRoot%\system32\inetsrv\ for 32 bit for 32 bit platform or to %SystemRoot%\SysWOW64\inetsrv for x86_64 platform.
3. Rename the directory extracted from the archive to PHP (possibly you will need to rename the old PHP directory to PHP.old)
4. Copy the php4ts.dll library from the PHP directory to your %SystemRoot%\system32 folder
