title: working with the php://stdin I/O streams
body: <p>I know the way to open and read the content of the file with the <code>fopen</code> function like this:</p>
  
  <pre><code>@fopen("inputfile.txt", "r");
  </code></pre>
  
  <p>But with the <code>php://stdin</code> i got bit confused</p>
  
  <pre><code>$in = fopen('php://stdin', 'r');
  </code></pre>
  
  <p>Where should i specify the name of <code>txt</code> file that i attempt to read?</p>
