Iterate through the string and count the number of capitalised letters.
You can do something like this (untested pseudocode)
$myStr = "Fred";
$numOfCapLetters = 0;
$curLetter = '';
for( $i = 0; $i <= strlen( $myStr ); $i++ ) {
$curLetter = $myStr{$i};
if( strtoupper( $curLetter ) == $curLetter ) {
$numOfCapLetters++;
}
}
then just compare the $numOfCapLetters for each string.
thnx,
Chris
