PHP数组对象stdClass的 - 回波值

所以我有这个数组保存在一个变量的标题 $改编。我想抓住或回声的价值[塞]

so I have this array saved in a variable title $arr. I want to grab or echo the value of [slug]

Array ( [0] => stdClass Object ( [term_id] => 11 
                                 [name] => Community Service 
                                 [slug] => community-service 
                                 [term_group] => 0 
                                 [term_taxonomy_id] => 11 
                                 [taxonomy] => category

所以，我想是这样的。

So i want something like this

回声$改编[塞]

然后将显示社区服务。我相信这是一件pretty容易，但我无法弄清楚如何抓住了数组stdClass的值，并将它显示在页面上。谢谢你。

which would then display "community-service". I am sure this is something pretty easy but i can't figure out how to grab the value out of an array stdClass and echo it on the page. Thank you.
