Some of above mentioned features have corresponding RFCs, in case, Validate conforms to those RFCs. For example email validation mostly covers RFC 822 or URI conforms to RFC 2396.

A few examples

Example 66-1. Validating an email address 

require_once 'Validate.php';

if (!Validate::email('johndoe@example.net')) {
    echo 'Invalid Email address';
} else {
    echo 'Its Valid!';
}

Example 66-2. Validating dates

In this example, date would first checked against desired format, and then get checked to see if it's not before "15 February 1986" or after "23 August 2008". 

require_once 'Validate.php';

var_dump(
    Validate::date(
        '121202',
        array(
            'format' => '%d%m%y',
            'min' => array('15', '02', '1986'),
            'max' => array('23', '08', '2008')
