Hi,

Can't find a PHP function to do just that. However, you can make one using [tt]preg_match[/tt]. Try this:

<?php

  function mixedCases($text) {
    if(preg_match("([A-Z])", $text))
      $upperCaseChars = true;
    else
      $upperCaseChars = false;

    if(preg_match("([a-z])", $text))
      $lowerCaseChars = true;
    else
      $lowerCaseChars = false;
   
    if($upperCaseChars && $lowerCaseChars)
      return true;
    else
      return false;
  }

$mixed = "ABCz";

if(mixedCases($mixed))
  echo "Mixed Cases in \"$mixed\"";
else
  echo "NOT Mixed Cases in \"$mixed\"";

?>

Good Luck
