How can the use of Prepared Statements in PHP prevent issues with data insertion into a database?

Using Prepared Statements in PHP can prevent issues with data insertion into a database by separating the SQL query from the user input. This helps to prevent SQL injection attacks and ensures that the data is properly sanitized before being inserted into the database. 

// Establish a database connection
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');

// Prepare a SQL statement with placeholders
$stmt = $pdo->prepare("INSERT INTO users (username, email) VALUES (:username, :email)");

// Bind the parameters with the actual values
$stmt->bindParam(':username', $username);
$stmt->bindParam(':email', $email);

// Set the values of the parameters
$username = 'john_doe';
$email = 'john.doe@example.com';

// Execute the statement
$stmt->execute();
