Been working on this one for a while but can't get it working properly. I need a regular expression to match if address is
1. PO Box
2. P.O. Box
3. P.O.Box
I'm using /i to make this case insensitive.
I got it working with 1 & 2, but it's still not matching 3. Any
suggestions?
if(preg_match( "/p[\.]o\.* +box/i", trim($_POST['address'])){
echo "Address is P.O. BOX";
}
