How can one optimize PHP MySQL queries for better performance?

To optimize PHP MySQL queries for better performance, you can consider using indexes on columns frequently used in WHERE clauses, optimizing your database schema, minimizing the number of queries by using JOINs and subqueries efficiently, and using prepared statements to prevent SQL injection attacks. 

// Example code snippet using prepared statements to optimize MySQL queries
$pdo = new PDO('mysql:host=localhost;dbname=my_database', 'username', 'password');

$stmt = $pdo->prepare('SELECT * FROM users WHERE id = :id');
$stmt->execute(['id' => 1]);
$user = $stmt->fetch();
