How can a beginner effectively learn and implement prepared statements in PHP?

To effectively learn and implement prepared statements in PHP as a beginner, you can start by understanding the concept of SQL injection and the importance of using prepared statements to prevent it. Next, you can practice creating and executing prepared statements using the PDO (PHP Data Objects) or mysqli extension in PHP. It's important to properly bind parameters to the prepared statement to ensure safe and secure database interactions. 

// Example of using prepared statements with PDO in PHP
$pdo = new PDO('mysql:host=localhost;dbname=database', 'username', 'password');
$stmt = $pdo->prepare('SELECT * FROM users WHERE email = :email');
$stmt->bindParam(':email', $email);
$email = 'example@email.com';
$stmt->execute();
$results = $stmt->fetchAll();
foreach ($results as $row) {
    echo $row['username'] . "<br>";
}
