php - 如何在 PHP/Blade for Laravel 中使用 Foreach 循环？

Question

这是一个简单的问题:有什么方法可以使用 foreach 循环或类似的东西来优化此代码吗？

@if(isset($tags[0]))
    <span class="label label-primary">{{ $tags[0] }}</span>
@endif
@if(isset($tags[1]))
    <span class="label label-primary">{{ $tags[1] }}</span>
@endif
@if(isset($tags[2]))
    <span class="label label-primary">{{ $tags[2] }}</span>
@endif
@if(isset($tags[3]))
    <span class="label label-primary">{{ $tags[3] }}</span>
@endif
@if(isset($tags[4]))
    <span class="label label-primary">{{ $tags[4] }}</span>
@endif
@if(isset($tags[5]))
    <span class="label label-primary">{{ $tags[5] }}</span>
@endif
@if(isset($tags[6]))
    <span class="label label-primary">{{ $tags[6] }}</span>
@endif
@if(isset($tags[7]))
    <span class="label label-primary">{{ $tags[7] }}</span>
@endif
@if(isset($tags[8]))
    <span class="label label-primary">{{ $tags[8] }}</span>
@endif
@if(isset($tags[9]))
    <span class="label label-primary">{{ $tags[9] }}</span>
@endif           

谢谢您，祝您度过愉快的一天/夜晚!
