由于echo数组，没有ajax响应

I have troubles with a website filter, where I would like to echo information of an array, but doing this the the ajax response will just stop.

我在网站过滤器上遇到了麻烦，我想要回显数组的信息，但是这样做ajax响应就会停止。

This is the array, that is printed with print_r

这是用print_r打印的数组

 Array ( 
    [0] => WP_Term Object ( 
    [term_id] => 181  
    [name] => Football 
    [slug] => football 
    [term_group] => 0 
    [term_taxonomy_id] => 181 
    [taxonomy] => activities 
    [description] => 
    [parent] => 0 
    [count] => 3 
    [filter] => raw )

Here is the code to print it this way:

下面是这样打印的代码:

$activities         =   get_the_terms($lesson_id,'activities',true);
print_r ($activities);

Now, I only want to print the name and I tried to use implode:

现在，我只想打印这个名字，我试着用内爆:

echo implode(', ',$activities) ;

But, with this line the Ajax response is empty. Same thing happens, when I simply echo one value from Array 0 or when I loop with foreach:

但是，使用这一行，Ajax响应是空的。同样的事情也会发生，当我简单地从数组0中返回一个值，或者当我用foreach循环时:

echo $activities[0]['name'];

The intention is to just print out the string "Football".

目的是仅仅打印出字符串“Football”。

Your print_r tell that the array contain a collection of WP_Term objects so you should use

print_r告诉数组包含一个WP_Term对象集合，因此应该使用它

 echo $activities[0]->name;
