How to make a simple output of categories?

Question

PHP

Hello everyone, how exactly can you simplify the code so that the category is simply taken from the database and displayed?

<?php if ($categories) { ?>
  <nav id="menu" class="navbar">
    <div class="navbar-header"><span id="category" class="visible-xs"><?php echo $text_category; ?></span>
      <button type="button" class="btn btn-navbar navbar-toggle" data-toggle="collapse" data-target=".navbar-ex1-collapse"><i class="fa fa-bars"></i></button>
    </div>
    <div class="collapse navbar-collapse navbar-ex1-collapse">
      <ul class="nav navbar-nav">
        <?php foreach ($categories as $category) { ?>
        <?php if ($category['children']) { ?>
        <li class="dropdown"><a href="<?php echo $category['href']; ?>" class="dropdown-toggle" data-toggle="dropdown"><?php echo $category['name']; ?></a>
          <div class="dropdown-menu">
            <div class="dropdown-inner">
              <?php foreach (array_chunk($category['children'], ceil(count($category['children']) / $category['column'])) as $children) { ?>
              <ul class="list-unstyled">
                <?php foreach ($children as $child) { ?>
                <li><a href="<?php echo $child['href']; ?>"><?php echo $child['name']; ?></a></li>
                <?php } ?>
              </ul>
              <?php } ?>
            </div>
             </div>
        </li>
        <?php } else { ?>
        <li><a href="<?php echo $category['href']; ?>"><?php echo $category['name']; ?></a></li>
        <?php } ?>
        <?php } ?>
      </ul>
    </div>
  </nav>
<?php } ?>

Answer 1

Somewhere you have an array of $categories being formed, obviously not in this code. There is no access to the database, html code is formed here.
Judging by the code, this is a bootstrap navbar, which forms a menu from your $categories array. Do you want to have 1 menu item?

Answer 2

See category controller. You can set your own sampling logic by looking at the model of this controller
