title: PDFLib giving an uncaught exception error
body: <p>I'm trying to get PDFlib support into PHP, but after finally figuring out how to install PDFlib, I get this error:</p>
  
  <pre><code>Fatal error: Uncaught exception 'PDFlibException' with message 'Function must not be called in 'object' scope'
  </code></pre>
  
  <p>Using the example code on <a href="http://us.php.net/manual/en/function.pdf-new.php" rel="nofollow noreferrer">php.net</a>: </p>
  
  <pre><code>&lt;?php
  // create handle for new PDF document
  $pdf = pdf_new();
  // open a file
  pdf_open_file($pdf, "test.pdf");
  // start a new page (A4)
  pdf_begin_page($pdf, 595, 842);
  // get and use a font object
  $arial = pdf_findfont($pdf, "Arial", "host", 1); pdf_setfont($pdf, $arial, 10);
  // print text
  pdf_show_xy($pdf, "There are more things in heaven and earth, Horatio,",50, 750);
  pdf_show_xy($pdf, "than are dreamt of in your philosophy", 50,730);
  // end page
  pdf_end_page($pdf);
  // close and save file
  pdf_close($pdf);
  ?&gt;
  </code></pre>
  
  <p>Does anyone have any ideas as to what could be causing this? I've tried googling around, but I've been unable to find any solutions.</p>
