Re: PHP and C

Why do you need to use stdin then? Couldn't you call the C program like this: <?php $someNumber = 1234; /path/to/cprogram $someNumber ?> and in your C program #include <stdio.h> int main(char **args, int argc) { int num = atoi(args[1]); // some processing printf("%d", numDerived); } On Sun, 19 Jul 2015 at 15:31 Ethan Rosenberg < erosenberg@hygeiabiomedical.com> wrote: > On 07/18/2015 05:40 AM, German Geek wrote: > > What do you actually want to achieve? > > > > On Sat, 18 Jul 2015 at 21:39 German Geek <geek.de@gmail.com> wrote: > > > >> Of course you need to give the variable $someNumber a value. > >> > >> On Sat, 18 Jul 2015 at 03:45 Ethan Rosenberg < > >> erosenberg@hygeiabiomedical.com> wrote: > >> > >>> Thanks - > >>> > >>> On 07/17/2015 12:34 AM, German Geek wrote: > >>>> You cannot run a C program and grab input from PHP interactively!
