Features:

This extension contains 3 functions that can be Cache features enabled or disabled respectively:

• PHP opcode cache – PHP is a script processing engine that reads an input stream containing text and/or PHP instructions and Produce another data stream (usually in HTML format). This means that the PHP engine on a web server must read, parse, compile and execute the PHP script for every request from the browser client. Reading, parsing, and compilation operations bring additional load to the web server’s CPU and file system, affecting the overall performance of PHP web applications. The PHP opcode (bytecode) cache is used to cache compiled script bytecodes in shared memory so that subsequent requests for the same script file can be reused by the PHP engine.
• File cache – Even if PHP bytecode caching is enabled, the PHP engine still needs to access the script files in the file system. When PHP scripts are stored on remote UNC file shares, file operations can incur significant performance overhead. The file cache of Windows Cache Extension for PHP can cache the contents of PHP script files in shared memory, reducing the file system operations of the PHP engine.
• Relative file path cache-PHP scripts frequently use relative paths to include or manipulate files. Every relative file path needs to be converted into an absolute file path by the PHP engine. When a PHP application uses many PHP files with relative paths, the operation of resolving relative paths to absolute paths can affect performance. Windows Cache Extension for PHP provides relative file path caching, reducing the number of conversions the PHP engine needs to do.
