operator question

[sodani]

I'm trying to figure out what the!== means in the following code. Can someone tell me?

if($_POST['CaptchaStr']!== $_POST['hash'])
print 'captchacorrect';
} else {
print 'captchaincorrect';
}

if($_POST['CaptchaStr']!== $_POST['hash'])

This is just comparing the $_POST['CaptchaStr'] to $_POST['hash'];

The!== as opposed to!= (or === as opposed to ==) just means that it also checks the type.

$one = '1';
$two = 1;

$one == $two (true)
$one === $two (false)
