What are best practices for improving the readability of PHP code when dealing with complex database queries?

Complex database queries can quickly become difficult to read and understand, making maintenance and debugging challenging. To improve readability, it's best to break down the query into smaller, more manageable parts. This can be achieved by using meaningful variable names, formatting the query for better visual organization, and adding comments to explain the purpose of each section of the query. 

// Example of a complex database query with improved readability

$query = "
    SELECT 
        users.id, 
        users.name, 
        COUNT(posts.id) AS post_count 
    FROM 
        users 
    LEFT JOIN 
        posts ON users.id = posts.user_id 
    WHERE 
        users.active = 1 
    GROUP BY 
        users.id 
    ORDER BY 
        post_count DESC
";

// Execute the query using your preferred method (e.g., PDO, mysqli)
