Question

大家新年快乐！这是我的代码。有没有办法通过循环来缩短代码？在循环中，第一个字段显示一次，相应的子字段显示5个元素。例如：第一个字段：Web浏览器子字段元素：firefox，chrome，IE，opera，maxthon

<div class="row">
<?php 
$sort=get_field('category');
         echo "<div class='bor'></div>
               <h3 style='text-align:center'>".$sort[ 0 ]['fenlei']."
               <a id='browser'></a></h3>
               <div class='bor'></div>";   
$websites = get_field('classification');
$row_count = count($websites);
   for ($i = 0; $i <= 4; $i++){
        include( get_stylesheet_directory() . '/template.php');
       }



?>

        </div>  
      <!--end row1-->
 <div class="row">
<?php 
$sort=get_field('category');
         echo "<div class='bor'></div>
               <h3 style='text-align:center'>".$sort[ 1 ]['fenlei']."
               <a id='browser'></a></h3>
               <div class='bor'></div>";   
$websites = get_field('classification');
$row_count = count($websites);
   for ($i = 5; $i <= 9; $i++){
        include( get_stylesheet_directory() . '/template.php');
       }



?>

        </div>  
      <!--end row2-->
 <div class="row">
<?php 
$sort=get_field('category');
         echo "<div class='bor'></div>
               <h3 style='text-align:center'>".$sort[ 2 ]['fenlei']."
               <a id='browser'></a></h3>
               <div class='bor'></div>";   
$websites = get_field('classification');
$row_count = count($websites);
   for ($i = 10; $i <= 14; $i++){
        include( get_stylesheet_directory() . '/template.php');
       }



?>

        </div>  
      <!--end row3-->

template.php的内容

<div class="col-lg-2dot4">
      <div class="thumbnail" style="height: 360px;">
        <a href="<?php echo $websites[ $i ]['link']; ?>" title=<?php echo $websites[ $i ]['name']; ?> target="_blank">
          <img src="<?php echo $websites[ $i ]['icon']; ?>" width="194" height="97" />
        </a>
        <div class="caption">
          <h3>
            <a href="<?php echo $websites[ $i ]['link']; ?>" title="Firefox" target="_blank"><?php echo $websites[ $i ]['name']; ?></a>
          </h3>
          <p><?php echo $websites[ $i ]['description'];; ?></p>
        </div>
        <ul class="list-inline text-center">
          <li style="list-style: none">Download:</li>
          <li>
            <a href="<?php echo $websites[ $i ]['download']; ?>" target="_blank">32Bit</a>
          </li>
        </ul>

      </div>
    </div>

Answer 1

可能没有意义，但功能是有序的：

function echoCode($sortIndex,$start,$stop) {
    $sort=get_field('category');
    echo "<div class='bor'></div>
        <h3 style='text-align:center'>".$sort[$sortIndex]['fenlei']."
        <a id='browser'></a></h3>
        <div class='bor'></div>";   
    $websites = get_field('classification');
    $row_count = count($websites);
    for ($i = $start; $i <= $stop; $i++)
        include( get_stylesheet_directory() . '/template.php');
}

然后用（0,0,4）和（1,5,9）调用两次。

<?php

function print_row($sort, $websites) {
  return function($limit_offset, $i) use($sort, $websites) {
    $start = $limit_offset[0];
    $end = $limit_offset[0] + $limit_offset[1];
    return "<div class='bor'></div>
            <h3 style='text-align:center'>"
      . $sort[$i]['fenlei']
      . "<a id='browser'></a></h3>
         <div class='bor'></div>"
      . implode('', array_map(range($start, $end), row_template($websites)));
    };
  }

  function row_template($websites) {
    return function($i) use($websites) {
      ob_start();
      include(get_stylesheet_directory() . '/template.php');
      return ob_get_contents();
    };
  }

  $sort = get_field('category');
  $websites = get_field('classification');
  $offsets = [[0, 4], [5, 4], [10, 4]];
  $results = array_map($offsets, print_row($sort, $websites));

  print implode('', $results);

通过循环缩短php代码
