Calling C/C++ library function from PHP
提问by Anon. BlackBerry Developer
We have a PHP web app running on a customer's machine. For an update, we have a bit of code in C that we'd like to include as a native opaque library along with the PHP web app.
我们有一个在客户机器上运行的 PHP Web 应用程序。对于更新，我们有一些 C 代码，我们希望将其作为本机不透明库与 PHP Web 应用程序一起包含在内。
How does one go about calling a C/C++ lib. function from PHP?
如何调用 C/C++ 库。PHP 的函数？
It cannot be assumed that the PHP app, called by the web server, has any sort of permission to call an exec(), eval(), or system() type of function to execute a C wrapper driver which in turn uses the C/C++ library, so it would need to be a direct C library use from within the PHP code.
不能假设由 Web 服务器调用的 PHP 应用程序具有调用 exec()、eval() 或 system() 类型的函数来执行 C 包装驱动程序的任何类型的权限，而后者又使用 C /C++ 库，因此它需要在 PHP 代码中直接使用 C 库。

The answer by St. John Johnson is correct. But you can now also us the php-cpp library. It offers a much easier bridge between PHP and C++. See http://www.php-cpp.comfor more information.
圣约翰约翰逊的回答是正确的。但是您现在也可以使用 php-cpp 库。它在 PHP 和 C++ 之间提供了一个更简单的桥梁。有关更多信息，请参阅http://www.php-cpp.com。

You can compile your code and use system, shell_exec or passthru functions to handle the output. Most web hosts allow you to compile c++ code, just ssh to your server, upload the code and compile it.
您可以编译代码并使用 system、shell_exec 或 passthru 函数来处理输出。大多数网络主机允许您编译 C++ 代码，只需 ssh 到您的服务器，上传代码并编译它。
