Question

I\'m starting with PHP for dynamic web pages. I have some libraries written in ANSI C for getting/setting parameters and other proprietary stuff. I wonder, is there a simple sol

Can you package your libraries into a DLL? If so, you can call them through PHP's COM api.

PHP COM Docs: http://us3.php.net/manual/en/book.com.php

Example Code:

Register("KERNEL32", "Beep", "i=ll", "f=s", "r=l");
$com->Beep(800, 10);

Otherwise you can write a extension that contains a custom wrapper function (ie, execute_through_wrapper('yourfunc')). Here is a doc on writing php functions in C.

Here is a quick tutorial on writing extensions in C. It shouldn't be too difficult to write a wrapper function. Once you created the extension, it can be loaded dynamically through dl() (very dangerous, and depreciated).

Those are the only options in your case. There isn't a linux equivalent (.so loader) of the dll loader (its a win32-related api call).
