Hex Validator

Zend\Validator\Hex allows you to validate if a given value contains only hexadecimal characters. These are all characters from 0 to 9 and A to F, case insensitive. There is no length limitation for the input you want to validate.

$validator = new Zend\Validator\Hex();
if ($validator->isValid('123ABC')) {
    // value contains only hex chars
} else {
    // false
}

Invalid characters

All other characters will return false, including whitespace and decimal points. Additionally, unicode zeros and numbers from other scripts than latin will not be treated as valid.
