Generally speaking, PHP cannot interact with random code. If you want
PHP to use entities defined in C, you must write a PHP extension and
ensure PHP is configured to use that extension.

Alternatively, you could just have your C program set some environment
variables; they will be accessible to PHP as members of the $_ENV
superglobal array.

Other alternatives include using shared memory (only on Unix) and
wrapping your C program into a Web service...
