Hello,

After playing with phpstan and seeing their stubs for some LDAP functions w=
ere
 wrong, I noticed that documentation for LDAP functions and stubs in
 ext/ldap/ldap.stub.php differs.

Especially in a lot of functions, the documentation states "string $dn =3D =
NULL"
 but the stub states non-nullable string parameter. Also, the ldap.stub.php
 file contains a lot of "string $bind_rdn =3D UNKNOWN" in places where the
 documentations states =3D NULL. What does UNKOWN mean here?

I would like to fix those conflicts.
Basically my questions are:
1) What is the difference between s and S in zend_parse_parameters and how =
do
 they behave for a NULL value?
2) What would changing =3D UNKNOWN to =3D NULL impact?
3) When a function like ldap_bind is called, is calling ldap_bind($link), a=
nd
 ldap_bind($link, NULL) changing anything else than ZEND_NUM_ARGS?
