Download the New Windows Cache Extension for PHP Beta

Perhaps you are a Web Developer or a Web Hoster who on the one hand likes PHP. But on the other hand you like Windows. It’s OK. It’s not a contradiction. Now you can run your PHP applications even better on Windows. It’s also OK to tell your Linux friends what they are missing.

Today, Microsoft is announcing the Windows Cache Extension for PHP Beta – a PHP accelerator that is used to increase the speed of PHP applications running on Windows and Windows Server. Once the Windows Cache Extension for PHP is enabled and loaded by the PHP engine, PHP applications can take advantage of the functionality without any code modifications. How sweet is that?

If you run PHP on Windows, check it out. If you run PHP on Linux and want an alternative, check it out. If you want to increase PHP application performance on Windows by caching PHP bytecode in memory, check it out. If you want to reduce file system I/O overhead by caching the PHP scripts in memory, check it out. If you want to avoid redundant mapping for absolute paths by using relative file path cache, check it out.

Windows Cache Extension for PHP Beta can be installed with the Microsoft Web Platform Installer 2.0 RC and works great with IIS 7.5, IIS 7.0, IIS 6.0 and IIS 5.1. Find more information on Using Windows Cache Extension for PHP. Also, be sure to check out other official IIS Extensions from Microsoft.

Windows Cache Extension for PHP

Windows Cache Extension for PHP is a PHP accelerator that is used to increase the speed of PHP applications running on Windows and Windows Server. Once the Windows Cache Extension for PHP is enabled and loaded by the PHP engine, PHP applications can take advantage of the functionality without any code modifications.

Increase PHP application performance on Windows by caching PHP bytecode in memory

Windows Cache Extension for PHP stores the PHP bytecode, the compiled version of the PHP script, in memory making it available when subsequent executions of the same script are needed helping to increase the overall PHP application performance. The use of Windows Cache Extension for PHP allows the PHP bytecode to be generated only once and to be reused each time the same PHP script is executed.

Reduce file system I/O overhead by caching the PHP scripts in memory

Windows Cache Extension for PHP helps to reduce the latency of file operations when PHP scripts are stored on remote UNC file shares. Windows Cache Extension for PHP includes a file system cache that is used to store the content of the PHP script files in shared memory, which reduces the amount of file system operations performed by PHP engine.

Avoid redundant mapping for absolute paths by using relative file path cache

Windows Cache Extension for PHP caches the relation between relative and absolute file paths, reducing the number of relative path resolutions performed by the PHP engine. PHP applications that use many relative paths would perform faster given the conversion to absolute paths is performed only once.

Features

  • PHP 5.2 and PHP 5.3 support
  • Configurable file cache
  • Configurable PHP opcode cache
  • Relative file path cache
  • PHP functions to obtain information about the cache status
