How can beginners in PHP effectively learn and implement form handling and database interactions?

Beginners in PHP can effectively learn and implement form handling and database interactions by following tutorials, reading documentation, and practicing with small projects. They can start by creating a simple HTML form that submits data to a PHP script for processing. The PHP script can then handle the form data, validate it, and interact with a database to store or retrieve information.

<?php
// Form handling
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $name = $_POST["name"];
    $email = $_POST["email"];
    
    // Database interaction
    $conn = new mysqli("localhost", "username", "password", "database");
    
    if ($conn->connect_error) {
        die("Connection failed: " . $conn->connect_error);
    }
    
    $sql = "INSERT INTO users (name, email) VALUES ('$name', '$email')";
    
    if ($conn->query($sql) === TRUE) {
        echo "New record created successfully";
    } else {
        echo "Error: " . $sql . "<br>" . $conn->error;
    }
    
    $conn->close();
}
?>

<form method="post" action="<?php echo $_SERVER["PHP_SELF"]; ?>">
    Name: <input type="text" name="name"><br>
    Email: <input type="text" name="email"><br>
    <input type="submit" value="Submit">
</form>
