Validation

Does anyone here have a recommended way of doing Validation Systems?
I have a simple registration page, and upon joining a validation email should be sent out. (Once) clicking the link inside the email, it adds you to the Members List...

Now, I was debating doing it that way, or I dont know how many of you have seen the new hotmail and all the (.NET Stuff which is cool)
But as opposed to sending out a validation email, they get you to
'Type the Code you See In The Box', I know they have to do it this way, because if you dont have an email account, they simply can't get you to validate your account w/ an email.

Anyways, so I was thinking either email validation, or getting some script to randomly generate a series of numbers & letters in a box, preferably 5 numbers/letters. The underneath that, get the user to
'type you last name exactly as you did above' which I guess in a sense, thats another way to validate too isn't it?

Anyways let me know your suggestions...
Regards,

Hi,

Most time the validation is used to verify that you have an existing email address.

The numbers as images are used to prevent automatic generation of user(etc.) accounts with bots. The scripts/bots can't read the images, the image codes are only human readable.
The generation of numbers as images is often referred as "CAPTCHA", try to search for that at http://www.phpclasses.org, there are several scripts of that kind.


Why and what for do you think you need that validation?
