It will work (the code below) with multiple changes, deletes, adds, but I don't
think it will work for multi-valued attributes, like say an object that contains
seven "location" attributes. The real key to understanding the PHP LDAP
functions is to understand PHP arrays, which are quite diffrent then is "base"
languages such as C. Arrays are "keyed", and each key value can contain one or
more values.
So $people["location"] = "Brighton";
$people["department"] = "IT\CIS";
would create a two VALUE, two KEY array that can be passed to
ldap_mod_whatever and will add/replace the location and department
attributes of the specified DN. Just setting the key like:
$people["location"] = "";
you can pass the array to ldap_mod_replace will remove the attributes
from the object.
You can multi-value with something like:
$people["location"][0] = "Brighton";
$people["location"][1] = "Detroit";
$people["location"][2] = "Saginaw";
is a three VALUE, one KEY array.
