// $test_string: the variable containing the string to do the search on 
// $caps_count: the variable that stores the count of uppercase chars 
// $caps_match: the array that stores all the regexp matches 
$test_string = "This Is My SPECIAL Test String"; 
preg_match_all("/[A-Z]/", $test_string, $caps_match); 
$caps_count = count($caps_match [0]); 
print "Uppercase Count: $caps_count"; 
// This will print "Uppercase Count: 12"

Useful snippet, thanks. Although the uppercase count should be 12.

Admin: thanks for catching that, it's been corrected.
