title: Execute .exe in php and fill input
body: <p>Firstly, sorry for my English.
  Is it possible to start .exe program with php script and pass input after the program has started. I can't use command line arguments.</p>
  
  <pre><code>#include &lt;iostream&gt;
  using namespace std;
  int main() {
      int a, b;
      cin&gt;&gt;a&gt;&gt;b;
      return a+b;
  }
  </code></pre>
