Title: Data content management and rich text editing through PHP and UniApp

Introduction:
In modern Internet applications, data content management and rich text editing are very common needs. This article will introduce how to use PHP and UniApp to implement such functions to help developers better manage and edit data in applications.

1. Introduction to UniApp
UniApp is a framework for developing cross-platform applications based on Vue.js. It supports a set of codes to be directly compiled into multiple platforms such as mini programs, H5, and Apps. Its advantage lies in rapid development and efficient operation, as well as a good user experience. In UniApp, we can use HTML, CSS and JavaScript to build the front-end interface, and interact with the background data by calling the interface.

2. PHP interacts with background data

1. Front-end and back-end data interaction methods
   In UniApp, we can use Ajax or uni.request to interact with the background data. In PHP, we can use methods such as $_POST or $_GET to obtain the data sent by the front end. The specific sample code is as follows:

uni.request({
url: 'http://www.example.com/api',
method: 'POST',
data: {

username: 'admin',
password: '123456'

},
success: (res) => {

console.log(res.data);

}
});

$username = $_POST['username']; // Get the username parameter passed by the front end
$password = $_POST['password']; // Get the password parameter passed by the front end
?>

2. Data storage and management
   In PHP, we can store and manage data through the database. Common database management systems include MySQL, MongoDB, etc. First, we need to connect to the database, and then operate the database through SQL statements. The sample code is as follows:

$conn = mysqli_connect("localhost", "username", "password", "database"); // Connect to the database
$sql = "SELECT * FROM users"; // Query all data in the users table
$result = mysqli_query($conn, $sql); // Execute SQL statements
while ($row = mysqli_fetch_assoc( $result)) {

echo $row['username'];

}
mysqli_close($conn); // Close the database connection
?>

3. Implementation of rich text editing function
In UniApp, we can use third-party components or custom components to implement rich text editing functions. Common rich text editors include UEditor, Quill, etc. The following is a sample code that uses the UEditor component to implement rich text editing functionality:
