How can PHP and SQL be effectively combined to create a dynamic and responsive web application?

To effectively combine PHP and SQL to create a dynamic and responsive web application, you can use PHP to interact with a database using SQL queries. By using PHP to retrieve and manipulate data from a database, you can dynamically generate content on your web application based on user input or other variables. 

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

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

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

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

// Output data from database
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo "ID: " . $row["id"]. " - Name: " . $row["name"]. "<br>";
    }
} else {
    echo "0 results";
}

// Close connection
$conn->close();
?>
