Question

我需要像这个例子一样的代码。我需要限制每个3类别。

<ul>
   <li>
      <div> Categpry 1 </div>
      <div> Category 2 </div>
      <div> Category 3 </div>
   </li>
   <li>
      <div> Categpry 4 </div>
      <div> Category 5 </div>
      <div> Category 6 </div>
   </li>
   <li>
      <div> Categpry y </div>
   </li>
</ul>

第1页 - ＆gt;类别1 [项目列表]，类别2 [项目列表]，类别3 [项目列表]

第2页 - ＆gt;类别4 [项目列表]，类别5 [项目列表]，类别6 [项目列表]

第x页 - ＆gt;类别y [项目列表]。

<?php
$category = array(
   array('category_name' => 'Category1', 'channel_name' => 'Item 1'),
   array('category_name' => 'Category3', 'channel_name' => 'Item 2'),
   array('category_name' => 'Category1', 'channel_name' => 'Item 2'),
   array('category_name' => 'Category3', 'channel_name' => 'Item 1'),
   array('category_name' => 'Category2', 'channel_name' => 'Item 2'),
   array('category_name' => 'Category4', 'channel_name' => 'Item 4'),
   array('category_name' => 'Category5', 'channel_name' => 'Item 5'),
   array('category_name' => 'Category1', 'channel_name' => 'Item 6'),
   array('category_name' => 'Category3', 'channel_name' => 'Item 7'),
   array('category_name' => 'Category2', 'channel_name' => 'Item 8'),
   array('category_name' => 'Category4', 'channel_name' => 'Item 8'),
   array('category_name' => 'Category3', 'channel_name' => 'Item 3'),
   array('category_name' => 'Category5', 'channel_name' => 'Item 4'),
   array('category_name' => 'Category6', 'channel_name' => 'Item 2'),
   array('category_name' => 'Category2', 'channel_name' => 'Item 5'),
   array('category_name' => 'Category2', 'channel_name' => 'Item 7')
);
$newOptions = array();
  $i=1;
    foreach ($category as $option) {
      $cname = $option['category_name'];
      $itemname = $option['channel_name'];

      $newOptions[$cname][$i] = $itemname;
 $i++;
    }
?>

PHP array_chunk（）无法帮助我，或者我没有使用它。

如何让这段代码在顶部做到。

如果您有消化症，请帮助我。 THX很多。

Answer 1

$pagesize = 3;

$category_pages = array_chunk($category, $pagesize);

echo "<ul>\n";
foreach ($category_pages as $page) {
    echo "\t<li>\n";
    foreach ($page as $category) {
        echo "\t\t<div> ", htmlspecialchars($category['category_name'], ENT_NOQUOTES, 'UTF-8'), " </div>\n";
    }
    echo "\t</li>\n";
}
echo "</ul>\n";

PHP array_chunk和每页限制
