PHP 5.3.6 released with changes for Windows users :VC++6 builds disabled
Officially VC++6 builds are dead (There are community builds but unsupported by core php developers)
Here is the announcement
Windows users: please mind that we do no longer provide builds created with Visual Studio C++ 6. It is impossible to maintain a high quality and safe build of PHP for Windows using this unmaintained compiler.
For Apache SAPIs (php5_apache2_2.dll), be sure that you use a Visual Studio C++ 9 version of Apache. We recommend the PHP builds as provided by ApacheLounge. For any other SAPI (CLI, FastCGI via mod_fcgi, FastCGI with IIS or other FastCGI capable server), everything works as before.Third party extension providers must rebuild their extensions to make them compatible and loadable with the Visual Studio C++9 builds that we no longer provide.
