I have never programmed PHP, so I cannot tell if the PHP ldap_delete() 
function is apropriate for deleting attribute values.

I have heard of a port of the Perl module perl-ldap to PHP.
I was told it was in PEAR (I assume this is the equivalent to CPAN for PHP)

Since in Perl perl-ldap allows the deletion of some/all attribute values 
together with other modfications in one LDAP modify operation I guess the PHP 
port will be capable of that too.
