Description
array 
ldap_explode_dn ( string dn, int with_attrib )
     ldap_explode_dn() function is used to split
     the DN returned by ldap_get_dn() and breaks
     it up into its component parts. Each part is known as Relative
     Distinguished Name, or RDN. ldap_explode_dn()
     returns an array of all those components.
     with_attrib is used to request if the RDNs
     are returned with only values or their attributes as well.  To
     get RDNs with the attributes (i.e. in attribute=value format) set
     with_attrib to 0 and to get only values
     set it to 1.
