title: FPDF library "Output" doesn't work?
body: <p>My problem with <code>[FPDF]</code> library is the next:</p>
  
  <pre><code>$pdf-&gt;Output("doc1.pdf","D");
  </code></pre>
  
  <p>In the above example I replaced the <code>D</code> with <code>I</code> or <code>S</code> or <code>F</code> the result is always the same: a popup appears to save or open the file.</p>
  
  <p>I want to save it without a popup into a specific directory.</p>
