" 解析错误: 语法错误，/home/site/public_html/devel/modules//filter.php 中的意外'{'第 35 行“

Question

我在 2 周前运行的脚本遇到了一个非常奇怪的问题，现在抛出以下错误：

"<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 /> "

这是代码，我已经看了数千遍，但我无法弄清楚其中有什么问题...

   <?php

define('_JEXEC',1); 
define('JPATH_BASE', realpath(dirname(__FILE__).'/../..' ));

require_once(JPATH_BASE.'/includes/defines.php');
require_once(JPATH_BASE.'/includes/framework.php');
$mainframe = JFactory::getApplication('site');
$mainframe->initialise();
$db = JFactory::getDBO();

ob_start();

header('Content-Type: application/json');


  function getCountries() {
     try {
       $db = JFactory::getDBO();
       $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) {

   }

     try {

       $db->setQuery($query);
       $result =  $db->loadRowList();

} catch (Exception $e) {
   $data = array('status'=>'error', 'tp'=>0, 'msg'=>$e->getMessage());

  echo json_encode($data);
}

ob_flush();
?>

谁能告诉我怎么了？

在 PHP 5.6 上解析良好。第 35 行是 finally 关键字。如果您的 PHP 版本早于 5.5，我想您会在这里遇到解析错误。
