My quick and dirty ucname (Upper Case Name) function.

<?php
//FUNCTION

function ucname($string) {
    $string =ucwords(strtolower($string));

    foreach (array('-', '\'') as $delimiter) {
      if (strpos($string, $delimiter)!==false) {
        $string =implode($delimiter, array_map('ucfirst', explode($delimiter, $string)));
      }
    }
    return $string;
}
?>
<?php
//TEST

$names =array(
  'JEAN-LUC PICARD',
  'MILES O\'BRIEN',
  'WILLIAM RIKER',
  'geordi la forge',
  'bEvErly CRuSHeR'
);
foreach ($names as $name) { print ucname("{$name}\n"); }

//PRINTS:
/*
Jean-Luc Picard
Miles O'Brien
William Riker
Geordi La Forge
Beverly Crusher
*/
?>

You can add more delimiters in the for-each loop array if you want to handle more characters.
