Validating utf 8 Xxx adal

03 Dec

It's rarely useful to validate a single character: usually, you'll want to validate a whole string.

You should name your function to avoid giving the impression that it checks for multi-character strings.

Edit: The output encoding doesn't have to be specified, it will be assumed to be UTF-8.

In Java, functions that perform a test and return a boolean are conventionally named . I'd have to somehow chunk it up into right-sized byte arrays first.

That's not really possible without examining the string using similar logic to what is in the function itself.

Defaults to true * Returns boolean * */ It evaluates the address in two parts, first evaluating the host and if that legal it then evaluates the user name.

If there is a DNS problem *and* the default $dns_check value of true is used, valid will fail.
