Changes made to Windows support

The minimum Windows version is now Windows 2000; Windows 98, ME and NT4 are no longer supported.

PHP Windows binaries target i586 or later. i386 and i486 are not supported.

Windows support has been added for the following functions:

Improved portability of stat(), touch(), filemtime(), filesize() and related functions (100% portable for the available data).

It's now possible to use hardlinks on Windows using the link() function, and symbolic links via the symlink() function. Hardlinks are available as of Windows 2000 and symbolic links as of Windows Vista.

The Windows version of PHP will expose a set of constants prefixed PHP_WINDOWS_*, a list of them and their usage can be found here.

The PDO_OCI php_pdo_oci8.dll library (for use with Oracle version 8 client libraries) is no longer being built. Instead, use php_pdo_oci.dll (note no '8') with Oracle 10 or 11 client libraries. Connection to other database versions is supported.

For the OCI8 extension, a new library php_oci8_11g.dll is available in addition to php_oci8.dll. Only one can be enabled at any time. Use php_oci8.dll with Oracle 10.2 client libraries. Use php_oci8_11g.dll with Oracle 11 client libraries. Connection to other database versions is supported.

There is now compiler support for Visual C++ 9 (VC9), using Visual Studio 2008.

There is now experimental support for x64 versions of PHP on Windows.

·Ù¹ð

Support for the ISAPI module have been dropped, use the improved and much better FastCGI sapi module instead.

Ãí°Õ: A new dedicated site for PHP on Windows, including downloads, release candidates and snapshots in various flavors (Thread-safe/not-thread-safe, VC6/VC9, x86/x64). The URL for this site is » http://windows.php.net/.
