Calling C programms from php

[Anon]

Hi,

In order to set up a secured billing system, I have to call from my php script a C program and make it returns a string.

In other words, my php script launches a C program passing it a string as its unique argument, the C program processes the string, and must returns it to the php script for further processing.

I don't konw how to do that, does anybody know where I should start from ? which parts of the php manual deal with this topic ?
Any code example to help me ?

Thanks for your help, folks :-)

Sure, just have your C program accept the string as a command-
line argument, and produce its result on stdout. Now you can
simply use backquotes to run it, just like in a shell script:

$result_string = my_c_prog arg1 arg2...;

Why can't you try build your C program as extension module. After that you dynamic load this lib and call functions.
