Answer from AI
A dynamic website is a web resource whose content is generated on the server at the time of user request or modified on the client side without reloading the page.
Main characteristics:
- Real-time content generation: The page is not a static HTML file but is assembled "on the fly" on the server.
- User interaction: Allows implementing logic that responds to user actions (registration, authorization, search, comments).
- Database interaction: Often uses DBMS for storing and retrieving content.
- Server-side programming languages: Uses languages such as PHP, Python, Ruby, Java, Node.js, and others for request processing and page generation.
- Client-side technologies: Actively uses JavaScript, AJAX for asynchronous content updates without reloading the entire page.
Examples of dynamic websites:
- Online stores
- Social networks
- Blogs with comments
- Forums
- News portals
Example of server-side code generating a dynamic page (PHP fragment):
<?php
// Connect to the database
$conn = new mysqli("localhost", "user", "password", "database");
// Retrieve data from the database
$result = $conn->query("SELECT title, content FROM articles WHERE id = " . $_GET['id']);
$article = $result->fetch_assoc();
// Generate HTML
echo "<h1>" . $article['title'] . "</h1>";
echo "<p>" . $article['content'] . "</p>";
$conn->close();
?>
Comparison with static sites:
| Characteristic | Dynamic site | Static site |
|---|---|---|
| Content | Generated on the server | Stored as ready HTML files |
| Interaction | High, based on logic | Low, only link navigation |
| Update | Easier to manage large data volumes | Requires manual file editing |
| Complexity | Higher | Lower |
| Performance | May be lower due to generation | Higher, as files are served immediately |
