[SOLVED] Multiple matches for an IF

[86Stang]

I'm building a member creation system and in lieu of using CAPTCHA I want to use a simple question that a bot could never answer.  In my form I ask the question 'Is water wet or dry?'.  Obviously the answer is 'wet' and I've got that check working well with the following:

 

if ($_POST['security'] != 'wet'){
	$message .= "<li>Your answer in the anti-spam field is incorrect.</li>";
}

 

But if they respond with 'Wet' it kicks back the above message because of the uppercase w.  So, do I need to do multiple IFs (and if so, how) or is there something where I can tell it to be case-insensitive?

if (strtolower($_POST['security']) != 'wet'){

So so simple...

 

Just so I can say I learned something here, what your solution does is takes whatever they entered into the security field and converts it to all lowercase?

That's correct
