I've got a little doubt. I'm searching for a mode for connecting to all kinds of databases using php and that i don't find anything helpfull. For instance I'm creating a platform and it'll be on a myriad of databases like Mysql or PostgreSQL varieties. It it is possible to solutions with this ? Thanks.

PHP's PDO extension has many drivers though some (Oracle for instance) are marked experimental.

The database adapter class in Zend Framework does an especially good job at abstracting connection particulars.

Use and abstract database library for example http://adodb.sourceforge.net/

You might try Doctrine

Database methods do not have a typical like HTTP does. To produce something similar to this, you should create an implementation for each database. Because of the number and diversity of these, this is very hard.
