Validation library PHP / Javascript -

One can recommend a PHP form validation library (which works independently outside of any php framework) That's all basic formatting (blank, vs. regex, email, alphanumeric and similar) JavaScript codes (ideally for working with jquery) to prepare the very same rules with the client side to validate the same type And therefore validation rules in singles

Thanks.

does this:

The entire form and validation rules in a PHP file Has been defined. Framework then generates HTML code with JavaScript validation and after submitting it does server-side validation.

You can also use different parts of the Framework separately as well.
