如何在foreach循環中只打印4個值？

Question

在foreach循環中可能有5或6個值，但我需要打印假設前5或6個值。我該怎麼做？

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

Answer 1

你應該試試這個：

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

希望這對你的工作！

Answer 2

如果你的關鍵是numenric和索引數組它可以直接做到像：

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

OR試試這個;

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

記住break;如果你有數組10元無需迭代後4迭代所以你應該打破的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

不必要的執行幫你。

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