What are some best practices for handling arrays in PHP, especially in the context of database queries?

When handling arrays in PHP, especially in the context of database queries, it is important to properly sanitize input data to prevent SQL injection attacks. One way to achieve this is by using prepared statements with parameterized queries. Additionally, it is good practice to validate and sanitize input data before using it in database queries to ensure data integrity and security. 

// Example of using prepared statements to handle arrays in PHP for database queries

// Assuming $db is your database connection

// Sample array of data to insert into the database
$data = [
    'name' => 'John Doe',
    'email' => 'johndoe@example.com',
    'age' => 30
];

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

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

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