    Don't know if anyone is interested in this, but this is a modified and more dynamic version of the posting below. Since ldap_dn2ufn takes ',' as delimiter for the UFNs, we'll also use it here. $pHowToBuild specifies, how the DN is going to be build.

    Short example:

    $myUFN = ldap_dn2ufn("cn=naaina, ou=container1, ou=container2, ou=container3, o=private, c=de");
    echo $myUFN . "\n"; // will return "naaina, container1, container2, container3, private, de"

    $myDN = $ldapObject->conv_ufn2dn($myUFN);
    echo $myDN . "\n"; // will return "cn=naaina,ou=container1,ou=container2,ou=container3,o=private,c=de"

    For the object name, $pHowToBuild["object"] is going to be used as prefix - for containers $pHowToBuild["container"] and for the last n elements $pHowToBuild["last"].

    <?php
          function ldap_ufn2dn (
           $pUFN,
           $pDelimiter = ",",
           $pHowToBuild = array(

            "container" => "ou",
            "last" => array("o", "c")

       if(!empty(    $pUFN)) {

                 $ufnArray = explode($pDelimiter, $pUFN);
                 $ufnLast  = count($ufnArray) - count($pHowToBuild["last"]);

                 /* Remove empty values */

    This function will convert "cn=bryan,ou=users,ou=admin,o=apachetoolbox" to "bryan,users,admin,apachetoolbox".

    The function of bryan will only work if you start with an Organization and using only an Organizational Unit as a container and the object is an CN.

    For example:

    $DN = "CN=DNS,CN=Authorized Login Methods,CN=Security";

    echo ($DN = ldap_dn2ufn($DN)) . "\n";

    echo ($DN = ldap_ufn2dn($DN)) . "\n";

    will echo:

    DNS,Authorized Login Methods,Security

    CN=DNS,OU=Authorized Login Methods,O=Security
