Retrieve the database rights from php?

Question

I'm thinking about some database management system, and my question is simple :

Is there a simple and reliable way to retrieve the access rights (write, readonly etc.), by a PHP code?

I haven't wrote any code yet, as this is just in my mind for now, that will just help me to structure some tables.

Answer 1

All database permissions are stored in a default mysql database: information_schema. Simply create a MySQL user who has permissions to view entries in this table, and use this user's login credentials when connecting from a PHP script. You can the retrieve permissions from the various permissions tables (which include DB level, table level, and column level permissions) to report back user rights. Something like:

SELECT * FROM`information_schema`.`user_privileges` WHERE`grantee` LIKE"'user'%";

Once you've run this query you can format the results however you'd like in PHP.
