The Windows Cache Extension 1.0 for PHP – RTW is available for download. This is a final, production-ready release that is provided under an open source BSD license with the source code hosted and maintained on http://pecl.php.net/packages/wincache/.
Install the Windows Cache Extension 1.0 for PHP – RTW
To install the Windows Cache Extension for PHP 5.2 and PHP 5.3, use the download links at the extension’s home page at http://www.iis.net/expand/WinCacheForPhp.
The installation with Web Platform Installer is the easiest as it will automatically place the extension binary into proper location and will update the PHP configuration to enable the extension. Also, if you have the beta or RC release of the extension installed, then Web PI will upgrade it. If you install any PHP application by using Web PI then the Windows Cache Extension for PHP will be offered as an optional component.
If you install the extension manually, then follow the instructions at Installing/Configuring WinCache for PHP.
- The extension can only be used with non-thread-safe builds of PHP
- The extension can only be used when IIS is configured to run PHP via FastCGI
- The Windows Cache Extension 1.0 for PHP 5.3 can only be used with the x86 VC9 build of PHP 5.3.
The WinCache extension is not supported by Microsoft Product Support Services. Instead it is supported as any other community PHP extension via the forums, mailing lists and the PECL bugs database. Use the following resources:
- To get help with installation, configuration and usage – WinCache documentation on php.net;
- To ask questions about the extension – WinCache forum on iis.net;
- To report a bug in the extension – PECL bug tracking system.
