Can there be any function maintained to extract database configuration within my code, something similar to
$db_user = drupal_get_dbuser();
$db_pass = drupal_get_dbpass();
...
...
The code with this is:
<?php
global $db_url;
$creds = parse_url($db_url);
print $creds['user'];
print $creds['pass'];
var_dump($creds);
?>
More in depth info and edge-cases are available by reading through the code of http://api.drupal.org/api/function/db_connect/6
