PHP Manual: Return first attribute

string ldap_first_attribute ( resource $link_identifier , resource $result_entry_identifier )

Gets the first attribute in the given entry. Remaining attributes are retrieved by calling ldap_next_attribute successively.

Similar to reading entries, attributes are also read one by one from a particular entry.

link_identifier: An LDAP link identifier, returned by ldap_connect.
result_entry_identifier
ber_identifier: ber_identifier is the identifier to internal memory location pointer. It is passed by reference. The same ber_identifier is passed to ldap_next_attribute , which modifies that pointer.

Note:
This parameter is no longer used as this is now handled automatically by PHP. For backwards compatibility PHP will not throw an error if this parameter is passed.

Returns the first attribute in the entry on success and FALSE on error.

Version	Description
5.2.4	The `ber_identifier` was removed. This is now handled automatically by PHP.
