my php-driven thoughts

Just remembered one thing: if you have home-made-hosting "company" and you provide MySQL databases as data storage server - don't use underscores (_) in databases' names. When you grant someone all priviledges on one db named user_db, then user can create even more databases, like:

• user0db;
  
• user1db;
  
• and so on...
  

I had that problem in my ex-work (Vilnius University IT Center). Thank God, i wasn't responsible for database administration (yet) .)

It's much better to gain such experience at 127.0.0.1 if u know what i mean .)
