[PHP] duplicating databases

[Steve Buehler]

	I am running PHP/MySQL for a program that I am writing.  We will have 
100's or 1000's of databases that will be duplicates in structure.  The 
problem is when I make a change to the database, I have to go to every 
database manually and make the change.  All of the databases start with 
"a_" and are on the same server.  I would like to be able to have one 
master database and then run a script when I make a change to it that will 
get the structure of the master database and check all of the other 
databases to make sure that their structures match.  If not, it will make 
the change to the other databases.  Does anybody know if there is all ready 
a program out there that would do this?  Can anybody point me in the right 
direction?  Or if it is only a few lines of script that somebody all ready 
has to do this, can you share it?

Thank You
Steve
