如何在PHP/Blade中为Laravel使用Foreach循环？

Question

这是一个简单的问题:有没有办法用foreach循环或类似的东西来优化这段代码？

@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           

谢谢你,祝你有个美好的一天/晚上!

Answer 1

你可以这样做:

@foreach ($tags as $tag)
    <span class="label label-primary">{{ $tag }}</span>
@endforeach

Answer 2

您可以使用@foreach循环（如其他答案所建议）或@for循环。使用blade控制结构语法（前面有@符号）

@for($i = 0; $i <= 9; $i++)
@if(isset($tags[$i]))
<span class="label label-primary">{{ $tags[$i] }}</span>
@endif
@endfor
