Just a note. That method only works if the string comprises only of letters
(will return false if a space or a number is in the string for example
regardless of whether all letters are uppercase)

That being the case then the solution FD posted would be best in my
opinion:-

if ($string == strtoupper($string))
{
echo 'is upper';
}
