Php 单击更改语言标志和文本

再问一个新问题

我还在那个项目网站上工作，我有一个简单的选择

我试图用当前语言在菜单上显示语言标志。只有国旗，没有文字（也许我们以后会想要）

现在，菜单的工作方式如下：

user\u box.php

    <?php trace(__FILE__,'begin'); ?>
<div id="userbox">
  <ul id="account_more_menu">

    <?php if(isset($_userbox_projects) && is_array($_userbox_projects) && count($_userbox_projects)) { ?>
    <li><a href="<?php echo get_url('dashboard', 'my_projects') ?>"><?php echo lang('my projects') ?></a>
      <ul>
<?php if (logged_user()->canManageProjects()) { ?>
        <li><a href="<?php echo get_url('project', 'add') ?>"><?php echo lang('add project') ?></a></li>
        <li><a href="<?php echo get_url('project', 'copy') ?>"><?php echo lang('copy project') ?></a></li>
<?php } // if ?>
        <li><span><?php echo lang('projects') ?>:</span></li>
    <?php if(100 > count($_userbox_projects)) { ?>
        <?php foreach($_userbox_projects as $_userbox_project) { ?>
        <li><a href="<?php echo $_userbox_project->getOverviewUrl() ?>"><?php echo clean($_userbox_project->getName()) ?></a></li>
        <?php } // foreach ?>
<?php } else { ?>
        <?php foreach($_userbox_projects as $_userbox_project) { ?>
<?php $name = clean($_userbox_project->getName()) ?>
<?php $url = clean($_userbox_project->getOverviewUrl()) ?>
<?php $first = strtoupper(substr($name,0,1)); ?>
<?php if (!array_key_exists($index, $first)) $index[$first]=array(); ?>
<?php $index[$first][] = array($name, $url); ?>
        <?php } // foreach ?>
        <?php foreach($index as $first => $items) { ?>
<li><a href=#><?php echo $first ?></a><ul>
          <?php foreach($items as $item) { ?>
        <li><a href="<?php echo $item[1] ?>"><?php echo $item[0] ?></a></li>
          <?php } // foreach ?>
</ul></li>
        <?php } // foreach ?>
<?php } // if ?>
<?php

  plugin_manager()->do_action('my_projects_dropdown');

现在我已经尝试了多种方法。但我似乎找不到正确的代码。基本上我想要的是改变图标（图片中的荷兰语标志）以改变为正确的语言标志。这将是赞成这样做，通过使用该精灵，但如果这将是太多，我可以只做单独的图像。我只是需要一些帮助来找出这个代码，让它工作。

这里：

我看不到任何
。flag
类。不，这是正确的。这是因为我不确定如何在那里实现flag类，它会根据选择的语言而变化。PHP并不是我最擅长的语言。HTML将非常有用，而不是最后一张图片。什么链接产生了这个代码？我编辑了这篇文章。完整的菜单代码现在在那里。所有必要的代码。这一行似乎与显示的菜单项列表相呼应。当我从代码中删除它时，菜单也不再列出。您可以在JSFIDLE中添加代码吗？
