PHP Array stdClass Object - Echo Value
提问by user982853
so I have this array saved in a variable title $arr. I want to grab or echo the value of [slug]
所以我把这个数组保存在一个变量 title 中$arr。我想抓取或回显 [slug] 的值
Array ( [0] => stdClass Object ( [term_id] => 11
[name] => Community Service
[slug] => community-service
[term_group] => 0
[term_taxonomy_id] => 11
[taxonomy] => category
So i want something like this
所以我想要这样的东西
echo $arr[slug]
回声 $arr[slug]
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.
然后将显示“社区服务”。我确信这很简单，但我不知道如何从数组 stdClass 中获取值并将其回显到页面上。谢谢你。

The array $arrcontains 1 item which is an object. You have to use the ->syntax to access it's attributes.
该数组$arr包含 1 个项目，它是一个对象。您必须使用->语法来访问它的属性。
echo $arr[0]->slug;
echo $arr[0]->slug;

Sorry, but you can do something more elegant.
对不起，但你可以做一些更优雅的事情。
foreach ($array as $obj)
{
// Here you can access to every object value in the way that you want
echo $obj->term_id;
}

Try simple following code...
尝试简单的以下代码...
echo $arr[0]->slug;
It supposed to be work because your array contain one object only.
它应该可以工作，因为您的数组只包含一个对象。

you can convert stdClass Object to php array like this and print any value.
您可以像这样将 stdClass 对象转换为 php 数组并打印任何值。
$php_array = json_encode($stdClass_object);
$php_array = json_decode($php_array,true);
echo "<pre>";print_r($php_array);
