PHP LDAP - 获取内部字段

Question

I have a LDAP system already in place that has some internal fields such as entryUUID. Is there anyway to retrieve the value of the fields as currently

$filter = "(mail=".$email.")";

$result = ldap_search($client_LDAP->client_ldap_connection, $base_dc, $filter);
$info = ldap_get_entries($client_LDAP->client_ldap_connection, $result);

doesn't display them only retrieves the main data (cn, ou, name, email ...etc)

Answer 1

You can retrieve them using '+' as attribute-name.

So you should be able to fetch them using ldap_search($client_LDAP->client_ldap_connection, $base_dc, $filter, ['+']);

Note that this will only retrieve the internal entries as no other attributes are defined within that last parameter to ldap_search.
