What are some examples of small web applications or projects that beginners can work on to apply their PHP knowledge and improve their programming abilities?

One example of a small web application that beginners can work on to apply their PHP knowledge is a simple to-do list manager. This project can help beginners practice CRUD operations (Create, Read, Update, Delete) in PHP and MySQL databases. By creating a web interface where users can add, edit, and delete tasks, beginners can improve their programming abilities and understand how data can be manipulated in a web application. 

<?php
// Connect to MySQL database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "todo_list";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Query to retrieve tasks from database
$sql = "SELECT * FROM tasks";
$result = $conn->query($sql);

// Display tasks in a list
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo "<li>" . $row["task_name"] . "</li>";
    }
} else {
    echo "0 results";
}

$conn->close();
?>
