PHP's filter_var, is it a good modern solution?

Question

How reliable is filter_var() ? Do you find it useful? Is it a good solution to validating a user's input?

Answer 1

Although I have not yet used it in any projects, I have tried it out a bit and all of the filters that I tried seem to work very well - and its a lot more elegant a solution than the messy regexes that I currently use. I certainly think it is quite a useful function that I will definitely be using in the future.
