How can beginners improve their understanding of PHP and MySQL integration, especially when working with HTML forms?

Beginners can improve their understanding of PHP and MySQL integration when working with HTML forms by practicing building simple CRUD (Create, Read, Update, Delete) applications. They can start by creating a basic form that collects user input, then use PHP to process the form data and interact with a MySQL database to store or retrieve information. By following tutorials, reading documentation, and experimenting with different scenarios, beginners can gradually enhance their skills in PHP and MySQL integration.

<?php
// Establish a connection to the MySQL 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);
}

// Process form data
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $name = $_POST['name'];
    $email = $_POST['email'];

    $sql = "INSERT INTO users (name, email) VALUES ('$name', '$email')";

    if ($conn->query($sql) === TRUE) {
        echo "New record created successfully";
    } else {
        echo "Error: " . $sql . "<br>" . $conn->error;
    }
}

$conn->close();
?>
