What are the advantages of using bind parameters in PDO for inserting array data into a MySQL database compared to traditional SQL queries in PHP?

When inserting array data into a MySQL database using traditional SQL queries in PHP, each value in the array needs to be concatenated into the query string, leaving the code vulnerable to SQL injection attacks. Using bind parameters in PDO helps prevent SQL injection by separating the query from the data values, ensuring that the values are properly escaped before being executed. 

// Sample array data to be inserted into the database
$data = [
    'name' => 'John Doe',
    'email' => 'john.doe@example.com',
    'age' => 30
];

// Prepare the SQL statement with bind parameters
$stmt = $pdo->prepare("INSERT INTO users (name, email, age) VALUES (:name, :email, :age)");

// Bind the array values to the parameters
$stmt->bindParam(':name', $data['name']);
$stmt->bindParam(':email', $data['email']);
$stmt->bindParam(':age', $data['age']);

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