How to call an executable file from a PHP script -

i want run php script calls executable cpp file on remote server.

i have tried below:

1.created cpp file

// function example #include <iostream> using namespace std;  int addition (int a, int b) {     int r;     r=a+b;     return r; }  int main () {     int z;     z = addition (5,3);     cout << "the result " << z;     return z; }  

generated .exe file , put in server's folder(test.exe)

step2 : created php scripts call exe file using 'shell_exec'

<?php  if (function_exists('shell_exec')){     echo "enabled"; } else {     echo "disabled"; } $file = 'test.exe'; if (!file_exists($file)) echo 'file not exists'; $out= shell_exec($file); //exec($file, $out); echo 'ouput is:: ' .$out;?> 

also, i've put php file on remote server , tried call php script in browser. shows error warning: shell_exec() [function.shell-exec]: unable execute 'test.exe'. want echo "ouput is:: 8".

please verify.

use:

exec("./test.exe", $out); 

note $out hold output.
remember thatshell_exec returns of output stream string, exec returns last line of output.
