LDAP controls support API

Hello, I’m looking into adding control support to all ldap operations in php-ldap. You can see a WIP PR here: https://github.com/php/php-src/pull/2640 Next step is to add control support for ldap_modify, ldap_add, ldap_search, … The historic patch for this added functions like ldap_modify_ext, ldap_add_ext… for this which I would like to avoid. So this means I cannot change the return type, only add parameters. One solution is to change: bool ldap_modify ( resource $link_identifier , string $dn , array $entry ) Into: bool ldap_modify ( resource $link_identifier , string $dn , array $entry, array $servercontrols, array $clientcontrols, array &$resultcontrols ) The problem is that it still does not give access to the result object and thus to errmsg and referrals which can be obtained with ldap_parse_result. So I was thinking maybe: bool ldap_modify ( resource $link_identifier , string $dn , array $entry, array $servercontrols, array $clientcontrols, [resource &$resultobject]) -> if the last parameter is omitted, it works as before, if it is given, then the user will have to call ldap_parse_result on it to get the information it wants. What do you think of this solution ? I don’t see any other giving access to all available information without BC. This will have to be changed for almost all ldap_* operations. Even ldap_bind can return controls in the result. Côme
