[PHP-DB] Getting last insert id?

[Chris Payne]

Hi there everyone,

I use the below to insert some data into my database:


mysql_query ("INSERT INTO forummessages (Postedby, email, subject, message, ForumID, 
posted, parentid) 
               VALUES ('$Postedby', '$email', '$subject', '$message', 
'$ForumID','$posted','$parentid')
");

But once it has done this, I need to get the id it has generated in the DB and then 
update that record with the id it generate, so how can I get the id from the above 
insert?

Any help would be greatly appreciated :-)

Regards

Chris
