[snip] I'm thinking of setting up an address-book on my server, but I'm not sure whether to use LDAP or MySQL. As I see it, LDAP is actually designed for this, and seems to have a more-or-less standard address-book format. On the other hand, I'm already using MySQL for several things, eg gallery2. But there doesn't seem to be any standard address-book format for SQL. Another thing, kmail and other mail clients seem to have standard LDAP interfaces. I'm using phpMyAdmin with MySQL, but there seems to be a PHP interface to LDAP too. I don't really like LDAP, but it seems the way to go. Is that right ... ? I'd be interested to hear your views. [/snip] First of all LDAP is not a database, it is a connection protocol that can connect to many things, most notably Active Directory seems to be the most popular usage. Therefore you cannot compare it to MySQL, because MySQL is a database product. Are you talking about Active Directory being the database? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
