PEAR or ADOdb

[kenny873]

there is an extension in PHP called PEAR, where we no longer need to connect to the DB using mysql_connect() but with
the embedded function such as DB:connect(), one of the main advantage is the ease of implementation if we want to change the db from mysql into Oracle....saves a lot of implementation time to rewrite!

I want to know the comparison of PEAR to ADOdb, which one is better to implement by their performance, functionality?

thanks
