In what ways can PHP5 and HTML5 be utilized to enhance the functionality and structure of a web application?

PHP5 can be used to handle server-side processing and logic in a web application, while HTML5 can be used to enhance the structure and user interface. By combining PHP5 and HTML5, developers can create dynamic and interactive web applications that are both functional and visually appealing. 

<?php
// PHP code to handle server-side processing
// Example: Fetching data from a database and displaying it on the webpage

// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

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

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

// Fetch data from the database
$sql = "SELECT id, name, email FROM users";
$result = $conn->query($sql);

// Display data in an HTML table
if ($result->num_rows > 0) {
    echo "<table><tr><th>ID</th><th>Name</th><th>Email</th></tr>";
    // output data of each row
    while($row = $result->fetch_assoc()) {
        echo "<tr><td>".$row["id"]."</td><td>".$row["name"]."</td><td>".$row["email"]."</td></tr>";
    }
    echo "</table>";
} else {
    echo "0 results";
}

$conn->close();
?>
