I am sick of connecting database in each script i need a more OOP approach to fetching database results. ex like wordpress use wpdb class to fetch results.

This what wordpress does to get data

<?php  $posts = $wpdb->get_results("SELECT ID, post_title FROM $wpdb->posts WHERE post_status = 'publish'


 AND post_type='post' ORDER BY comment_count DESC LIMIT 0,4")
?>

How can i create the same feature too using any class or function

and use it in my script

Thank you
