wordpress打印自定义数组

Question

我正在使用wordpress插件来显示有关商家的信息。但我只想在页面中显示很少的字段。

$post_id = the_ID();<br/>
$customContent  = get_post_custom($post_id);<br/>

返回：

Array (<br/> 
[_yoast_wpseo_google-plus-description] => Array ([0] =>)<br/>

)<br/> 
<br/> 

如何打印网站（bs_website），twitter（bs_twitter），facebook（bs_facebook）？我在论坛中尝试了一些帮助，但只显示了“数组”。

提前致谢。

你试过这个吗？

<?php $meta_values = get_post_meta($post_id, $key, $single); ?>
