Using PHP and SQLite to implement Web Suite and CMS
In the modern Internet era, website development has become a very important task. To simplify the website development process, we can use ready-made web kits and CMS. In this article, we will introduce how to use PHP and SQLite to implement a simple web suite and CMS.
Web suite and CMS are tools that help developers quickly build websites and manage content. By using web suites and CMS, we can reduce development time, improve development efficiency, and have good scalability and maintainability.
First, we need to install PHP and SQLite. PHP is a popular server-side scripting language, while SQLite is a lightweight embedded database engine. Once installed, we can start coding our website.
First, we create an index.php file. In this file, we will implement the home page of the website. We can use a mixture of HTML and PHP to write web content.
<!DOCTYPE html>
<html>
<head>
<title>Web套件和CMS</title>
</head>
<body>
<h1 id="欢迎来到我们的网站">欢迎来到我们的网站</h1>
<?php
// 使用SQLite查询数据库
$conn = new SQLite3('database.db');
$result = $conn->query('SELECT * FROM articles');
while ($row = $result->fetchArray()) {
echo '<h2 id="row-title">' . $row['title'] . '</h2>';
echo '<p>' . $row['content'] . '</p>';
}
?>
</body>
</html>In this code, we use the PHP extension of SQLite to connect and query the database. The database file here is named database.db and can be modified according to your own needs.
In the database, we created a table named articles to store articles on the website. The table contains two fields: title and content, which are used to store the title and content of the article respectively. We can use SQLite query statements to obtain data from the database and display it on the web page.
Next, we can create an admin.php file to implement the background management function of the CMS. In this file, we can implement the functions of adding, editing and deleting articles.
<!DOCTYPE html>
<html>
<head>
<title>CMS后台管理</title>
</head>
<body>
<h1 id="CMS后台管理">CMS后台管理</h1>
<form action="admin.php" method="post">
<input type="text" name="title" placeholder="请输入文章标题"><br>
<textarea name="content" placeholder="请输入文章内容"></textarea><br>
<input type="submit" value="添加文章">
</form>
<?php
// 处理文章的添加
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
// 获取用户输入的标题和内容
$title = $_POST['title'];
$content = $_POST['content'];
// 将文章插入数据库
$stmt = $conn->prepare('INSERT INTO articles (title, content) VALUES (:title, :content)');
$stmt->bindValue(':title', $title);
$stmt->bindValue(':content', $content);
$stmt->execute();
// 刷新页面
header('Location: admin.php');
}
// 显示已有的文章列表
$result = $conn->query('SELECT * FROM articles');
while ($row = $result->fetchArray()) {
echo '<h2 id="row-title">' . $row['title'] . '</h2>';
echo '<p>' . $row['content'] . '</p>';
echo '<a href="edit.php?id=' . $row['id'] . '">编辑</a>';
echo '<a href="delete.php?id=' . $row['id'] . '">删除</a>';
}
?>
</body>
</html>In this code, we first create a form in which users can enter the title and content of the article and submit the form to add a new article.
When submitting the form, we insert the title and content entered by the user into the database. SQLite prepared statements are used here to prevent SQL injection attacks.
Then, we query the database and display the existing article list on the web page. At the end of each article we have added edit and delete links.
So far, we have completed the simple web suite and CMS. By using PHP and SQLite, we can quickly build websites and manage content.
Of course, this is just a simple example, you can extend and modify the code to add more functions and pages according to your needs. At the same time, you can also use other database engines such as MySQL to replace SQLite.
I hope this article can help you quickly get started with the development of web suites and CMS. I wish you success on the road to website development!

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
