It depends on how your C program receive and output the data...
Program execution functions, Process control functions, pipes, shared memory... it's up to you to choose.

or maybe even writing an extension. The php source code package provides a lot of examples of them.

all extensions are in the directory ext/
start by analyzing a simple extension like tokenizer
http://www.php.net/manual/en/zend.php will help you understand esp. the macros.
There's also a script ext_skel (or ext_skel_win32.php) that helps you creating your own extension

Have you looked at the pear package Inline_C?

Or if you want to run the compiled program in php, then you can probably use [php_man]shell_exec[/php_man]

Can anybody explain to me step by step what i have to do to integrate C in PHP 'coz i've try to read the php manual u guys suggested, especially
http://www.php.net/manual/en/zend.php. It is to complicated for me to understand especially now i'm running out of time.

Actually, my project is to develop a consultancy info system, where user have to enter their username and password to use the system (in php environment). So then i want to encrypt the password using an algorithm called ECC in C language. That is why i need to integrate C in PHP.

Do you think that's possible? i mean i want to sent the password which user entered to the C program to be encrypt and then send it back to the php program to compare it with the password in the database.

Please help me! I need to know what setting i have to do?
Can i just use Borland Turbo C++? I've try to run simple extension tokenzier using Turbo C++ as suggested by mr. volka, but there are so many error like "unable to open include file PHP.h"!

What can i do? Is there any setting that i need to do first?
