Looking for a comprehensive PHP form validation class

Hello,
Please can you suggest me a comprehensive PHP form validator class? I'm searching for something powerful and easy to use with the following validation features:

Alphanumeric (uppercase, lowercase, numbers, spaces, special chars and a mix of them)
Credit Card number (most used CC: Visa, Mastercard, etc.)
Date / Time (min/max date, min/max time; date and time format choice)
E-mail address
Entry length (min/max length)
FIle extension
Like entry (compare two fields, as in password confirm)
Number (decimal separator [dot or comma], min/max, # of decimals allowed)
Required (the field can't be blank)
URL (protocols allowed or ignored)
Zip code (5 digits, 9 digits, etc.)

Seems impossible to have all these features in one class, uh?

Ops! Addy, I forgot to mention that I'll be on a shared host: can I still use PEAR if I have no way to install it?

i think you can use PEAR just by including files only,

I don't think that you require installation for that.

Hope this helps

Yes, seems that it works even without installation... but the script is excellent on few things and cuts off other useful validations...
I.e., there are a lot of methods to validate TLDs in different ways, but there are no validations for credit card, entry length, file extension, compare fields, zip... :-(

I must admit, all the validations I'm searching for are yet included in a Dreamweaver extension I purchased some years ago... But I'm trying to leave Dreamweaver to rely on hand-coding to avoid junk, but since I'm a PHP newbie I have no idea how to "convert" that long script in a easy-to-use class...

Anyway, the PEAR worked and I'm happy to know a thing more :-)
