title: PHP Startup: Unable to load dynamic library
body: <p>I have notice I started getting this error message in my error log:</p>
  
  <pre><code>PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/local/lib/php
  /extensions/no-debug-non-zts-20060613/pdf.so' - /usr/local/lib/php/extensions
  /no-debug-non-zts-20060613/pdf.so: cannot open shared object file: No such file
   or directory in Unknown on line 0
  </code></pre>
  
  <p>The error goes into the log every time you open the main page but everything seems to be working. Does anyone have any ideas what might cause this error to occur, I have been change the code in the past few days but when read back though I can't find anything that could be the cause.</p>
  
  <p>there's nothing on the page that I have changed for when it initially loads but i have changed things in areas where I have if (isset...etc.</p>
  
  <p>Any possible suggestions are appreciated. what type of command might this error message be caused by?</p>
