PHP development: How to implement article reading statistics function

PHP development: How to implement article reading statistics function, specific code examples are required

Introduction:
In the process of website or application development, it is often necessary to review articles Statistics of reading volume are conducted to understand user attention and article popularity. This article will introduce how to use PHP to develop and implement the article reading statistics function, and provide specific code examples.

1. Create database table
   First, we need to create a database table to store the reading statistics of the article. Suppose we already have a table named "articles" with the following structure:

CREATE TABLE articles (
    id INT AUTO_INCREMENT,
    title VARCHAR(255),
    content TEXT,
    view_count INT DEFAULT 0,
    PRIMARY KEY (id)
);

2. Display article content and reading volume
   In the page that displays article content, we need to simultaneously Display the text content and reading volume of the article. The following is a simple sample code:

<?php
// 获取文章ID
$articleId = $_GET['id'];

// 更新阅读量
$pdo = new PDO('mysql:host=localhost;dbname=your_database', 'your_username', 'your_password');
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

$stmt = $pdo->prepare('UPDATE articles SET view_count = view_count + 1 WHERE id = :id');
$stmt->bindParam(':id', $articleId);
$stmt->execute();

// 获取文章内容及阅读量
$stmt = $pdo->prepare('SELECT * FROM articles WHERE id = :id');
$stmt->bindParam(':id', $articleId);
$stmt->execute();

$article = $stmt->fetch(PDO::FETCH_ASSOC);

// 显示文章内容及阅读量
echo '<h1 id="article-title">'.$article['title'].'</h1>';
echo '<p>'.$article['content'].'</p>';
echo '<p>阅读量：'.$article['view_count'].'</p>';
?>

3. Update reading volume
   When a user accesses an article page, we need to update the reading volume field in the database to achieve reading statistics . Taking the SQL statement in the above code as an example, we can add the following code to the PHP file of the article page:

$articleId = $_GET['id'];

$pdo = new PDO('mysql:host=localhost;dbname=your_database', 'your_username', 'your_password');
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

$stmt = $pdo->prepare('UPDATE articles SET view_count = view_count + 1 WHERE id = :id');
$stmt->bindParam(':id', $articleId);
$stmt->execute();

This code will get the article ID and use the UPDATE statement to read the corresponding article. Add 1 to the quantity field.

4. Display reading volume
   To display the reading volume on the article page, we only need to add the output of the view_count field after obtaining the article content. Refer to the following code:

$articleId = $_GET['id'];

$pdo = new PDO('mysql:host=localhost;dbname=your_database', 'your_username', 'your_password');
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

$stmt = $pdo->prepare('SELECT * FROM articles WHERE id = :id');
$stmt->bindParam(':id', $articleId);
$stmt->execute();

$article = $stmt->fetch(PDO::FETCH_ASSOC);

echo '<h1 id="article-title">'.$article['title'].'</h1>';
echo '<p>'.$article['content'].'</p>';
echo '<p>阅读量：'.$article['view_count'].'</p>';

Through the above code, we can display the reading volume of the article on the article page.

Conclusion:
This article introduces how to use PHP to develop and implement the article reading statistics function, and provides specific code examples. By creating database tables, updating readings, and displaying readings, we can easily count the readings of articles. I hope this article will be helpful to you in implementing the article reading statistics function in the PHP development process.
