解析错误：语法错误，footer.php 中出现意外的“<”

Question

我收到此错误：

解析错误：语法错误，/home/.../public_html/lagatar.com/wp-content/themes/.../footer.php 中出现意外的 '

在我的footer.php 中添加了facebook 的likebox 代码后，我的网站页脚下方出现了上述错误。

<?php

/* Prevent direct access to this file */
if ( !defined('WP_CONTENT_DIR') )
    die('Please do not access this file directly.');

<div id="fb-root"></div>
<script>(function(d, s, id) {
  var js, fjs = d.getElementsByTagName(s)[0];
  if (d.getElementById(id)) return;
  js = d.createElement(s); js.id = id;
  js.src = "//connect.facebook.net/en_US/sdk.js#xfbml=1&appId=204491109624023&version=v2.0";
  fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>

/* WordPress and a lot of plugins require the function in this file, so I guess we have to use it :-(. */
wp_footer();


Display::body_close();

Display::html_close();

您不小心在 PHP 标记中插入了 HTML，您应该这样做：

<?php    
/* Prevent direct access to this file */ if ( !defined('WP_CONTENT_DIR') )  die('Please do not access this file directly.');    
?>

<div id="fb-root"></div> <script>(function(d, s, id) {  var js, fjs = d.getElementsByTagName(s)[0];  if (d.getElementById(id)) return;  js = d.createElement(s); js.id = id;  js.src = "//connect.facebook.net/en_US/sdk.js#xfbml=1&appId=204491109624023&version=v2.0"; fjs.parentNode.insertBefore(js, fjs); }(document, 'script', 'facebook-jssdk'));</script>

<?php    
/* WordPress and a lot of plugins require the function in this file, so I guess we have to use it :-(. */ 
wp_footer();

Display::body_close();

Display::html_close();
