我正在尝试在我的 wordpress 选项中回显数组第二级的设置，并且在获取变量时遇到了一些麻烦。此代码确实有效：
<?php foreach($area['fields'] as $field): ?>
<?php if ($field['id'] == 'show_border')
{echo ' show_border';} ?>
<?php endforeach; ?>
这只是检查是否有一个字段询问您是否要显示边框，是否有任何我想要的回声，无论该字段设置为实际显示边框与否。
我要做的只是回显在“show_border”字段中设置的值。
知道我会怎么做吗？

我正在尝试获得类似 ["id"]=> "show_border" 的值并回显它的值。
