这是一个很难问的问题，但是，让我们尝试一下。我正在将此模块用于 joomla 我需要为它创建一个覆盖，以便它获取第一个结果

<?php foreach( $pages as $key => $list ): ?>

并将其放在自己的 div 中并继续执行该语句。请询问是否需要任何其他信息，这是覆盖的完整代码：

非常感谢任何帮助。

你可以做这样的事情。基本上，设置一个布尔值只做与第一项不同的事情：

<?php $first = true; ?>
<?php foreach( $pages as $key => $list ): ?>
<?php 
    if($first) {
        /* put this $list in its own div or whatever you need to do */
        $first = false;
    } else {
        ... //the default operation/code
?>
...
<?php } ?>
<?php endforeach; ?>

完整编辑：

使用计数器知道它是哪个迭代：

<?php $c = 0; // initialize counter
foreach( $pages as $key => $list ): 
if ($c++ == 0):
?>
this section will only run for the first element.

<?php endif;?>
