如何在foreach循环中只打印4个值？

Question

在foreach循环中可能有5或6个值，但我需要打印假设前5或6个值。我该怎么做？

<div class="tag-area">       
     @foreach(explode(',',$product->tags) as $tag)       
      <span>{{$tag}}</span> 
     @endforeach      
</div> 

Answer 1

你应该试试这个：

<div class="tag-area">       
    @foreach(explode(',',$product->tags) as $key => $tag) 
     @if($key <= 5)       
      <span>{{$tag}}</span> 
     @endif 
    @endforeach      
</div> 

希望这对你的工作！

Answer 2

如果你的关键是numenric和索引数组它可以直接做到像：

<div class="tag-area">       
    @foreach(explode(',',$product->tags) as $key => $tag) 
     @if($key <= 5)       
      <span>{{$tag}}</span> 
     @else 
     <?php break; ?> 
     @endif 
    @endforeach 

OR试试这个;

<div class="tag-area"> 
<?php $cnt == 0; ?> 
@foreach(explode(',',$product->tags) as $tag) 
    <span>{{$tag}}</span> 
    <?php 
    $cnt++; 
    if($cnt >= 5) 
    break; 
    ?> 
@endforeach 

记住break;如果你有数组10元无需迭代后4迭代所以你应该打破的foreach迭代

<div class="tag-area">       
    @foreach(explode(',',$product->tags) as $key=>$tag) 
     @if($key >= 4) 
      @break 
     @endif 
     <span>{{$tag}}</span> 
    @endforeach      
</div> 

Answer 3

不必要的执行帮你。

<div class="tag-area">       
     @foreach(explode(',',$product->tags) as $key => $tag) 
      @if($key <= 5)       
       <span>{{$tag}}</span> 
      @endif 
     @endforeach      
    </div>
