The selected answer is too complicated. Laravel has a simpler solution:
选择的答案太复杂了。Laravel 有一个更简单的解决方案：
{{ $items->pluck('tag')->implode(', ') }}

implode()is good for echoing simple data. In real project you usually want to add some HTML or logic into the loop, use $loopvariable which is available since 5.3:
implode()适合回显简单数据。在实际项目中，您通常希望在循环中添加一些 HTML 或逻辑，使用$loop自 5.3 以来可用的变量：
@foreach ($arrayOrCollection as $value)
{{ $loop->first ? '' : ', ' }}
<span class="nice">{{ $value->first_name }}</span>
@endforeach

Use implode:
使用内爆：
{{ implode(', ', $tags) }}

Use this. We can implement it using $loop->last
用这个。我们可以使用$loop->last来实现它
@foreach ($arrayOrCollection as $value)
<span class="nice">
{{ $value->first_name }}
@if( !$loop->last)
,
@endif
</span>
@endforeach

Try implode():
尝试内爆（）：
$arr = ['one', 'two', 'three'];
echo implode(',', $arr);
// output
// 输出
one,two,three

I believe what you are looking for might be something like this: //have your array in php tags //$arr = ['one', 'two', 'three']; ? > //go through the array with foreach and if the count of the array is not equal to the las element then put coma after it
我相信你正在寻找的可能是这样的： //在 php 标签中有你的数组 //$arr = ['one', 'two', 'three']; ? > // 使用 foreach 遍历数组，如果数组的计数不等于 las 元素，则在其后放置 coma
@foreach ($arr as $key => $value)
@if( count( $arr ) != $key + 1 )
{{ $value }},
@else
{{ $value }}
@endif
@endforeach
