"<br /> <b>Parse error</b>: syntax error, unexpected '{' in <b>/home/site/public_html/devel/modules//filter.php</b> on line <b>35</b><br /> "

I'm facing a really weird issues with a scripts which worked 2 weeks ago and now is throwing the following error:

"<br /> <b>Parse error</b>: syntax error, unexpected '{' in <b>/home/site/public_html/devel/modules/filter.php</b> on line <b>35</b><br /> "

This is the code and I've had a look thousand of times but I can't figure out what's wrong in it ...

   <?php

ob_start();

  function getCountries() {
     try {

       $query = "SELECT id, name FROM `#__countries`";
       $db->setQuery($query);
       $result =  $db->loadRowList();
       if(!$result) {
         throw new exception("Country not found.");
       }
       $res = array();
          foreach($result as $key=>$value) {

     } 
     finally {

Can someone tell me what's wrong ?

That parses fine on PHP 5.6. Line 35 is the finally keyword. If your PHP version is older than 5.5 I imagine you would get a parse error here.
