    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

    $dn="${dn}cn=$value,";
    } elseif ($key == $LastKey) { //last variable, so it's the O
    $dn="${dn}o=$value";
    } elseif ($value == "") { //value is blank, so continue
    continue;
    } else { //just a typical OU
    $dn="${dn}ou=$value,";
    }

    };
    return $dn;

    }

    $unf=".bryan.users.admin.apachetoolbox";
    $dn=ldap_unf2dn($unf);
    print "$dn" // will give me "cn=bryan,ou=users,ou=TS,o=apachetoolbox"

    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(
    "object" => "cn",
    "container" => "ou",
    "last" => array("o", "c")
    )
    )
    {
    $resultDN = null;

    if(!empty(    $pUFN)) {
    /* Check $pHowToBuild */
    if(is_array($pHowToBuild)) {
    /* Check if required keys are existent */
    if(array_key_exists("object", $pHowToBuild) &&
    array_key_exists("container", $pHowToBuild) &&
    array_key_exists("last", $pHowToBuild))
    {
    $ufnArray = explode($pDelimiter, $pUFN);
    $ufnLast = count($ufnArray) - count($pHowToBuild["last"]);

    /* Remove empty values */
    foreach($ufnArray as $objKey => $objVal)
    if(empty(    $objVal))
    array_splice($ufnArray, $objKey, 1);

    /* Now build the DN ... */
    foreach($ufnArray as $objKey => $objVal) {
    $objVal = trim($objVal);

    if(    $objKey == 0) {
    /* For the object */
    $resultDN .= $pHowToBuild["object"] . "=" . $objVal . ",";
    } elseif (    $objKey >= $ufnLast) {
    /* For last parts of the DN */
    $resultDN .= $pHowToBuild["last"][$objKey - $ufnLast] . "=" . $objVal;
    if((    $objKey - $ufnLast - 1) != 0) {
    $resultDN .= ",";
    }
    } else {
    /* For containers */
    $resultDN .= $pHowToBuild["container"] . "=" . $objVal . ",";
    }
    }
    }
    }
    }

    return     $resultDN;
    }
    ?>
