How to use PHP to implement the automatic recommendation function of friend links in the CMS system

In the CMS system, friend links are a way of mutual recommendation and cooperation, which can increase interaction and traffic between websites. Traditional friend link operations require manual addition and management, but with the development of the Internet, we can use the PHP programming language to implement the automatic recommendation function of friend links and improve the user experience of the website.

Below, I will introduce how to use PHP to implement the automatic recommendation function of friend links in the CMS system, and provide code examples as a reference.

Step 1: Create a database table

First, we need to create a database table to store information about friend links. You can create a table named links, containing the following fields:

CREATE TABLE links (
  id INT(11) AUTO_INCREMENT PRIMARY KEY,
  title VARCHAR(255) NOT NULL,
  url VARCHAR(255) NOT NULL,
  description TEXT,
  logo VARCHAR(255),
  status ENUM('active', 'inactive') DEFAULT 'active',
  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
  updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
);

Step 2: Set friend link recommendation rules

According to needs, we can set some friend link recommendation rules, for example, according to Recommendations based on traffic volume, website themes, etc. Here, we will use pageviews as the recommendation rule.

Step 3: Write PHP code

Next, we will use PHP code to implement the function of automatic recommendation of friend links. First, create a file named links.php, and then write the following code:

<?php
// 连接数据库
$connection = mysqli_connect('localhost', 'username', 'password', 'database_name');
if (!$connection) {
    die('数据库连接失败：' . mysqli_connect_error());
}

// 获取推荐的友链
$query = "SELECT * 
          FROM links 
          WHERE status = 'active' 
          ORDER BY views DESC 
          LIMIT 5";
$result = mysqli_query($connection, $query);

// 输出友链列表
if (mysqli_num_rows($result) > 0) {
    while ($row = mysqli_fetch_assoc($result)) {
        echo '<a href="' . $row['url'] . '">' . $row['title'] . '</a>';
    }
} else {
    echo '暂无推荐的友链。';
}

// 关闭数据库连接
mysqli_close($connection);
?>

Step 4: Call the friend link automatic recommendation function in the CMS system

Finally, we need to The links.php file is called in the relevant page to display the recommended list of friend links. You can use the php include statement to include it, or copy the code directly to the page where you need to display the friend link.

<div class="sidebar">
    <h3 id="友情链接">友情链接</h3>
    <?php include 'links.php'; ?>
</div>

When the page loads, the friend link automatic recommendation function will obtain and display the friend link list from the database according to the set rules.

Summary:

By using PHP to implement the automatic friend link recommendation function of the CMS system, we can save the tedious steps of manually adding and managing friend links, improve the user experience of the website, and increase the website interactions and flows. The above code examples can be used as a reference to implement the automatic recommendation function of friend links, and can be modified and optimized according to actual needs.
