Second-hand recycling websites use the browsing history function developed in PHP to improve user experience

In recent years, with the increasing number of second-hand transactions, second-hand recycling websites have become a popular platform for people to buy and sell idle items. However, as the number of users continues to increase, the user experience requirements for websites are also constantly increasing. In order to improve the user experience, second-hand recycling websites began to use PHP to develop browsing history functions to help users find the products they are interested in more conveniently.

The browsing history function is an important user experience improvement tool, which allows users to better track their browsing history for future search and reference. By recording users' browsing history, the website can accurately recommend relevant products to users and improve the user's shopping experience.

Below, we will use a code example to demonstrate how to use PHP to develop the browsing history function. First, we need to create a file named "browsing_history.php" to handle browsing history related operations.

<?php
session_start();

function add_to_browsing_history($item_id) {
  // 获取之前的浏览记录
  $browsing_history = isset($_SESSION['browsing_history']) ? $_SESSION['browsing_history'] : [];

  // 将当前商品添加到浏览记录
  if (!in_array($item_id, $browsing_history)) {
    array_unshift($browsing_history, $item_id);
  }

  // 限制浏览记录长度为10
  if (count($browsing_history) > 10) {
    array_pop($browsing_history);
  }

  // 更新浏览记录
  $_SESSION['browsing_history'] = $browsing_history;
}

function get_browsing_history() {
  // 返回浏览记录
  return isset($_SESSION['browsing_history']) ? $_SESSION['browsing_history'] : [];
}

// 添加到浏览记录
add_to_browsing_history($_GET['item_id']);

// 获取浏览记录
$browsing_history = get_browsing_history();
?>

In the above code, we use PHP session to store the user's browsing history. In the add_to_browsing_history function, we first obtain the previous browsing record, and then add the currently viewed item to the front of the browsing record. In order to limit the length of browsing records, we use the array_pop function to delete the oldest items.

In addition, in the above example, we used $_GET['item_id'] to obtain the item ID browsed by the user. In actual application, you can modify this part of the code to suit your needs based on the specific conditions of your website.

When a user views a product on a second-hand recycling website, we only need to add some corresponding code to the corresponding product details page to call the browsing record function. For example, we can add the following code to the bottom of the product details page:

<div class="browsing-history">
  <h2>最近浏览</h2>
  <ul>
    <?php foreach ($browsing_history as $item_id): ?>
      <li><a href="/item.php?id=<?php echo $item_id; ?>"><?php echo $item_id; ?></a></li>
    <?php endforeach; ?>
  </ul>
</div>

The above code displays the user's browsing history at the bottom of the product details page. The user can quickly jump by clicking on the link in the browsing history. Go to the previously viewed product page.

Through the above code examples, we can see that it is very simple to use PHP to develop the browsing history function in a second-hand recycling website. By recording the user's browsing history, the website can more accurately recommend products of interest to the user and improve the user's shopping experience. In this way, the user experience of second-hand recycling websites will be significantly improved, and users will be able to browse and purchase the products they need more conveniently.
