title: Cannot Save File to directory using FPDF
body: <p>I won't break out or show the lengthy code in actually building the PDF itself because I know the file generation is working fine.</p>
  
  <p>When I try the following:</p>
  
  <pre><code>$pdf-&gt;Output('abc.pdf', 'F');
  </code></pre>
  
  <p>I receive error: </p>
  
  <blockquote>
    <p>FPDF error: Unable to create output
    file: abc.pdf</p>
  </blockquote>
  
  <p>By changing the Output destination to 'D' or 'I':</p>
  
  <pre><code>$pdf-&gt;Output('abc.pdf', 'D');
  </code></pre>
  
  <p>The user is prompted to download the pdf that was generated and is done so successfully (views fine). The error makes me think it is a permissions error but fpdf should have access to write a pdf file to the directory the action is already occurring in correct?</p>
  
  <p>Anybody dealt with this before?</p>
