How do I make a variable all lower case?

[Anon]

I need to take in a variable entered in a form (say a name) and convert it to all lower case. So I can do a bunch of if statements like:
if($name == "jeff"){
echo "You are Jeff";
}
if($name == "matt"){
echo "You are Matt";
}

anyone who can help I will greatly appreciate it. Thanks.
