PHP development: How to implement article reading statistics and ranking functions

Article reading statistics and ranking functions are very common on many blogs, news websites and forums. This article will introduce how to use the PHP language to implement these two functions and provide specific code examples.

1. Article reading statistics function

  1. Create database table

First, we need to create a table in the database to store article information , including fields such as article ID, title, content, and reading volume. The following is a simple SQL statement used to create this table:

CREATE TABLE `articles` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `title` varchar(255) NOT NULL,
  `content` text NOT NULL,
  `views` int(11) NOT NULL DEFAULT '0',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
  1. Increase reading volume

When a user visits the article details page, we need to increase the number of reads of the article Reading volume. This can be achieved by using the following code in the PHP processing file on the article details page:

// 获取文章ID
$articleId = $_GET['id'];

// 更新文章的阅读量
$sql = "UPDATE articles SET views = views + 1 WHERE id = $articleId";
$result = mysqli_query($conn, $sql);

In the above code, we first get the ID of the article from the URL parameter, and then use the UPDATE statement to update the reading field of the article .

2. Article Reading Ranking Function

  1. Query Ranking

To realize the ranking function of article reading, we need to base on the reading of the article Use the volume field to query the most read articles. The following is a simple SQL statement used to query the ranking list:

$sql = "SELECT id, title, views FROM articles ORDER BY views DESC LIMIT 10";
$result = mysqli_query($conn, $sql);

In the above code, we use the query statement to sort the 10 most read articles in descending order and limit the number of query results to 10.

  1. Display rankings

Next, we need to display the queried results on the page. You can use the following code to achieve this:

// 遍历查询结果并输出
while ($row = mysqli_fetch_assoc($result)) {
  echo "<li>{$row['title']} (阅读量:{$row['views']})</li>";
}

In the above code, we use a while loop to traverse each query result, and use the echo statement to output the title and reading volume of the article to the page.

Summary

Article reading statistics and ranking functions are one of the basic functions that many websites must have. We can easily implement both of these features with the code examples provided in this article. Using PHP language and MySQL database combined, not only can simple reading statistics and rankings be achieved, but also further optimization and expansion can be carried out according to needs. Hope this article is helpful to you!

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.
