What are some resources or tutorials available for optimizing SQL query handling in PHP?

When working with SQL queries in PHP, it is essential to optimize them to improve performance. One way to optimize SQL query handling in PHP is to use prepared statements instead of directly inserting variables into the query string. Prepared statements help prevent SQL injection attacks and can improve query execution time. 

// Example of using prepared statements to optimize SQL query handling in PHP

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

// Prepare a SQL query with a placeholder
$stmt = $pdo->prepare('SELECT * FROM users WHERE email = :email');

// Bind the parameter value to the placeholder
$email = 'example@email.com';
$stmt->bindParam(':email', $email);

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

// Fetch the results
$results = $stmt->fetchAll();

// Loop through the results
foreach ($results as $row) {
    // Process each row
}
