String Question

[Mateobus]

I just want to do a Boolean check of a string that returns true if the last two characters of the string are upper case and false otherwise. Thanks.

You can do it with preg_match() too, but this is probably one of the easiest ways:
[code]
$text = 'abCD';

// Make sure the string is always 2 characters or more otherwise substr() returns false
if (ctype_upper(substr($text, -2)) {
       echo "The string $text last 2 characters consists of uppercase letters.\n";
   } else {
       echo "The string $text last 2 characters do not consist of uppercase letters.\n";
   }
[/code]

<?php
$blah = "abcdef";

$test = substr($blah, -2);
if (ctype_upper($test)) {
echo "letters are uppercase";
}
else { echo "letters are not uppercase"; }
?>

edit: gah! you beat me :(
