As anyone who works with user input knows, not everyone who submits information makes it look proper. One one of my web forms, I parse all the needed fields that I wish to be title cased; their name, address, city, etc. I use this to perform this action, which works nicely: PHP Code: CODE $string = ucwords(strtolower($string)); This fixes the input if the user types in all caps or all lowercase. There is a problem I have been noticing about those who enter a generation after their name, such as "Bill Warner III". The above function changes it to "Bill Warner Iii", which is incorrect. I have been toying with a regular expression to catch these I's (or sometimes V's) and turn them all uppercase, but to no avail. Here are versions of my non-working code: PHP Code: CODE $string = preg_replace("/\b([IiVv])+\b/e", strtoupper("$1"), $string);
$string = preg_replace("/\b([IiVv]+)\b/e", strtoupper("$1"), $string);
$string = preg_replace("/\b([IiVv]+)$/e", strtoupper("$1"), $string) Thanks,kivarnerexpress

This pattern should match almost any Roman numeral below L/50 (it is unlikely you will ever encounter anything beyond, say, 10th/X generation names). CODE /\b(i+|i+[vx]*?|v[i]*?|x+[vi]*?)\b/ei Here's a quick example (the names are, of course, randomly chosen). Note that the 'strtoupper()' function is being evaluated as PHP code and is enclosed in quotes. CODE <?php
$names = array(
'john sMith iv',
'Richard jones Iiv',
'JOE NOBODY II',
'Viva vivi ixen ivan III',
'Person XI',
'person xv'
);
$pattern = '/\b(i+|i+[vx]*?|v[i]*?|x+[vi]*?)\b/ei';
for( $i=0;$i<count($names);$i++ ) {
$name = ucwords(strtolower($names[$i]));
$string = preg_replace($pattern, 'strtoupper("$1")', $name);
$names_p[$names[$i]] = $string;
}
print_r($names_p);
?> Outputs: QUOTE Array
(
[john sMith iv] => John Smith IV
[Richard jones Iiv] => Richard Jones IIV
[JOE NOBODY II] => Joe Nobody II
[Viva vivi ixen ivan III] => Viva Vivi Ixen Ivan III
[Person XI] => Person XI
[person xv] => Person XV
)

Script That Tracks The User Status

long explaination: hey, I'm building a user profile site right now. And, I kinda know how to
