PHP-CPPPHP 开发扩展 C++ 库

PHP-CPP是一个用于开发PHP扩展的C++库。它提供了一套详实易用的类，用于开发PHP扩展。详细文档说明：http://www.php-cpp.com

示例1：

Php::Value hello_world(){

    return "hello world!";}

示例2：

#include <phpcpp.h>



/**

 *  Global variable that stores the number of times 

 *  the function updateCounters() has been called in total

 *  @var    int

 */

int invokeTotalCount = 0;



/**

 *  Global variable that keeps track how many times the

 *  function updateCounters() was called during the

 *  current request

 *  @var    int

 */

int invokeDuringRequestCount = 0;



/**

 *  Native function that is callable from PHP

 *

 *  This function updates a number of global variables that count

 *  the number of times a function was called

 */

void updateCounters()

{

    // increment global counters

    invokeTotalCount++;

    invokeDuringRequestCount++;

}



/**

 *  Switch to C context, because the Zend engine expects get get_module()

 *  to have a C style function signature

 */

extern "C" {

    /**

     *  Startup function that is automatically called by the Zend engine

     *  when PHP starts, and that should return the extension details

     *  @return void*

     */

    PHPCPP_EXPORT void *get_module() 

    {

        // the extension object

        static Php::Extension extension("my_extension", "1.0");

        

        // install a callback that is called at the beginning 

        // of each request

        extension.onRequest([]() {

            

            // re-initialize the counter

            invokeDuringRequestCount = 0;

        });

        

        // add the updateCounter method to the extension

        extension.add("updateCounters", updateCounters);

        

        // return the extension details

        return extension;

    }

}
