I need to have a code like this example. I need to limit 3 category per li.

<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>

Page 1 -> Category 1 [Items list], Category 2 [Items list], Category 3 [Items list]

Page 2 -> Category 4 [Items list], Category 5 [Items list], Category 6 [Items list]

Page x -> Category y [Items list].

<?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'),

Answer 1

$pagesize = 3;

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

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