how to obtain an ldap address & modify it through PHP

Hi all,

I'm currently trying to make a webbased addressbook thingie, i've managed to
get it to search through existing addresses, but i was wondering how i can
modify them.

I know the dn & all the other things about the inetOrgPerson entries, but
i'm abit at a loss how to obtain the resource pointing to the entry i need.

Does anyone know some good docs on this? the manual isn't really helping me
out :(

Cheers
