Explode() array issue

Below is my config. I am connecting through php to AD LDAP server for authentication. the ldap part works like a dream. I used the explode function to drop all the excess baggage with the user to only get me the display name, but I am unable to turn this into an array or some other way to sort the info. I know explode is suppose to make the variable an array, but i think because i'm in a loop, it is erasing the data


<?

/******globals needed for included pages***/

global $displayname;
//$user =& JFactory::getUser();

/*************Ens of globals needed for included pages***/


    $dn = "CN=Sales_Managers,OU=CINET,OU=Carousel Everyone,DC=CHARLESTOWN,DC=CAROUSELINDUSTRIES,DC=com";

    $attributes = array("displayname","member", "1");

    $filter = "(cn=*)";

    $ad = ldap_connect("10.0.25.250")
          or die("Couldn't connect to AD!");
  
    ldap_set_option($ad, LDAP_OPT_PROTOCOL_VERSION, 3);
    ldap_set_option($ad, LDAP_OPT_SIZELIMIT, 500);

    $bd = ldap_bind($ad,"administrator@charlestown.carouselindustries.com","c@r0us3L")
          or die("Couldn't bind to AD!");

    $result = ldap_search($ad, $dn, $filter, $attributes);

    $entries = ldap_get_entries($ad, $result);

// Specify Variable and begin
    $a=0;
    
    //Create your loop for $a
    do
    {
    
    //Grab all the Members array of the user logged in and store
   $member=$entries[0]["member"][$a];
        
        
    //$member=$entries[0]["member"][0];
    // Explode $members to grab only the CN name
    $member1=explode ("CN=",$member);
    $member2=explode (",",$member1[1])

    //echo $member . "<br>";
    //echo $member1[1] . "<br>";
    $members3[$a]=array($members2[0]);
    //echo $members3;
    echo $member2[0] . "<br>";
    print_r ($members3);
    echo $a;
    $a++;
}
while($a<50);
     ldap_unbind($ad);
     ?>

I also would like to add tat i did a print_r($member2); and got this....

Array ( [0] => Gregg Coleman [1] => OU=ALB Users [2] => OU=ALB Office [3] => OU=Carousel Everyone [4] => DC=CHARLESTOWN [5] => DC=CAROUSELINDUSTRIES [6] => DC=com )

Array ( [0] => Chris Jenkins [1] => OU=ALB Users [2] => OU=ALB Office [3] => OU=Carousel Everyone [4] => DC=CHARLESTOWN [5] => DC=CAROUSELINDUSTRIES [6] => DC=com )

Ultamitly, I would like to take the names which are Array[0] and put them in an array for sorting so that I put them in a dropdown box

Thanks
