Calling C/C++ library function from PHP
<p>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.</p>

<p>How does one go about calling a C/C++ lib. function from PHP? </p>

<p>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. </p>
