I've downloaded ZF2 framework but there is no Zend\Validator\Alnum
class in \library\Zend\Validator
directory. But the manual says it must be there:
// Basic usage
// A basic example is the following one:
$validator = new Zend\Validator\Alnum();
if ($validator->isValid('Abcd12')) {
// value contains only allowed chars
} else {
// false
}
Is this normal or they've changed their framework but forgot to change manual? Where can I find it?
