Since it involves code examples, I will first provide a sample code framework, and then explain the function and implementation of each part.

<?php
// Database Connectivity
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "dbname";
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Publish updates
if(isset($_POST['post'])) {
    $content = $_POST['content'];
    $sql = "INSERT INTO posts (content) VALUES ('$content')";
    $conn->query($sql);
}

// Get all updates
$sql = "SELECT id, content FROM posts";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo "ID: " . $row["id"]. " - Content: " . $row["content"]. "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
?>

<!DOCTYPE html>
<html>
<head>
    <title>QQ space function demonstration</title>
</head>
<body>
    <h1>Post updates</h1>
    <form method="post" action="">
        <textarea name="content"></textarea>
        <input type="submit" name="post" value="Post">
    </form>

    <h1>All updates</h1>
    <?php
        // Show all updates
        $sql = "SELECT id, content FROM posts";
        $result = $conn->query($sql);
        if ($result->num_rows > 0) {
            while($row = $result->fetch_assoc()) {
                echo "ID: " . $row["id"]. " - Content: " . $row["content"]. "<br>";
            }
        } else {
            echo "No updates yet";
        }
    ?>
</body>
</html>

This is a simple sample code that implements the basic function of QQ space: users can post updates and view the updates of all users.

In this code, it mainly includes the following parts:

Database connection: Connect to the MySQL database and replace the user name, password and database name with appropriate values.
Publish dynamics: When the user clicks the publish button, the dynamic content entered by the user is inserted into the database.
Get all updates: Display the updates posted by all users on the page, including the ID and content of the updates.
HTML part: including input box and publish button. Users can write dynamic content in the input box and publish it through the button.

This code can be further improved, such as adding user authentication, comment function, like function, etc. I hope this simple example can help you better understand how to use PHP to implement functions similar to QQ Space.
