note 109482 modified in function.ldap-explode-dn by yannick

I came accros this page and enjoyed the comments. 

Since a LDAP string can sometimes be lengthy and have many attributes, I needed to be able to sort through all that is in.

In my case, I needed to get the subdomain part and other parameters. 

Here is how I built my method.
<?php
 /**
 * Parse, and format a DN string to Array
 *
 * Read a LDAP DN, and return an array keys
 * listing all similar attributes.
 *
 * Also takes care of the character escape and unescape
 *
 * Example:
 * CN=username,OU=UNITNAME,OU=Region,OU=Country,DC=subdomain,DC=domain,DC=com
 *
 * Would normally return:
 * Array (
 * [count] => 9
 * [0] => CN=username
 * [1] => OU=UNITNAME
 * [2] => OU=Region
 * [5] => OU=Country
 * [6] => DC=subdomain
 * [7] => DC=domain
 * [8] => DC=com
 * )
 *
 * Returns instead a manageable array:
 * array (
 * [CN] => array( username )
 * [OU] => array( UNITNAME, Region, Country )
 * [DC] => array ( subdomain, domain, com )
 * )
 *
 *
 * @author gabriel at hrz dot uni-marburg dot de 05-Aug-2003 02:27 (part of the character replacement)
 * @author Renoir Boulanger
 * 
 * @param string $dn The DN
 * @return array
