You know, I'm not really sure what question is being asked here...  Can
you restate the question?

Again, not sure what was asked.  But, from a real quick look at the PHP
documentation for their LDAP functions, I'm not sure their API is powerful
enough to accomplish what we've been saying (issuing a pointed delete and
add  (or replace)) in one function call.  Might be better asked on a PHP
mailing list... I'm not a bigtime PHP coder.

While the observation isn't too helpful I'm sure, it's fairly easy to
accomplish with an API like Perl's Net::LDAP.
