Best way is using mysql_pconnect().

I like how oracle drivers works with tns names.
You have a connection pool for a unique name (can have more than 1 different pool). Then you can tell your app to use that pool for each operation. The drivers itself handle reconnection (can be achieved with mysql_pconnect).
