查看报错文件的第 2 行，代码如下

<pre class="wp-block-syntaxhighlighter-code">

<?php echo config('facebook_code'); ?>

</pre>
3、决定在线调试，决定按照数组格式打印此变量 
<pre class="wp-block-syntaxhighlighter-code">

<?php print_r(config('facebook_code')); ?>

</pre>



Array ( [name] => FacebookMessenger [facebook_code] =>


)
4、当 echo 时，其参数会强制转换为字符串。现在是数组转换为字符串失败。当修改为如下代码时，不再报错 
<pre class="wp-block-syntaxhighlighter-code">

<?php echo config('facebook_code')['name']; ?>

</pre>
