php - 按顺序在 5 个项目后添加 div

Question

我需要在每 5 个项目后添加一个 div 标签。任何人都可以为这一逻辑提供任何帮助吗？我已经尝试过，但没有成功。

我有这个代码:

<div class="product-grid">
    <?php foreach ($products as $product) { ?>
    <div class="item">.....</div>
    <?php } ?>
  </div>

我明白了

<div class="product-grid">
    <div class="item">.....</div>
    <div class="item">.....</div>
    <div class="item">.....</div>
    <div class="item">.....</div>
    <div class="item">.....</div>
    <div class="item">.....</div>
    <div class="item">.....</div>
    <div class="item">.....</div>
    <div class="item">.....</div>
    <div class="item">.....</div>
    <div class="item">.....</div>
 </div>

看起来像这样:(按顺序在 5 个项目后添加一个 div。)

<div class="product-grid">
    <div class="item">.....</div>
    <div class="item">.....</div>
    <div class="item">.....</div>
    <div class="item">.....</div>
    <div class="item">.....</div>
    <div class="clearfix visible-xs-block"></div>
    <div class="item">.....</div>
    <div class="item">.....</div>
    <div class="item">.....</div>
    <div class="item">.....</div>
    <div class="item">.....</div>
    <div class="clearfix visible-xs-block"></div>
    <div class="item">.....</div>
 </div>

一些帮助将不胜感激。

<?php 
// control variable 
$counter = 0;
?>
<div class="product-grid">
    <?php foreach ($products as $product) { ?>
        <div class="item">.....</div>
        <?php 
        // on every #5 result
        if(++$counter % 5 === 0) { ?>
          <div class="clearfix visible-xs-block"></div>
        <?php  
        }
    } 
    ?>
  </div>
