[php Classes]

Does anyone know where I can have a good read about how classes work in php.

Because I have a few questions.

Do they get held across requests or do they get destroyed once the response has been sent?

Why we have an OO way of writing and a procedural way of writing something.

Is the OO way faster? smarter? Or is it purely readiblity?

If anyone has a good grounding in this topic, please send me a link to some information about it.

[Need help connecting to mysql]

I would download mysql 5.0.

I'd use the new extension mysqi which is the improved extension.

Finally I'd use mysqli_connect.

Take a look at php.net and do some reading on mysqli and it's methods and properties.

[simple query help [solved]]

Would have been a bit more help if you gave us the the columns of both tables. This will get u started.

SELECT *
FROM djs
WHERE NOT EXISTS
(

SELECT *
FROM djsweek
WHERE djsweek.name = djs.name

)

[application structure and error handling]

How can I redirect a user to a generic webpage stating that an error has occurred.

I looked at header("Location: ") but the problem is it throws if I've already started sending data to them.

How does everyone else do it?
