[SOLVED] lowercase usernames

[wafflestomper]

If I want each user to sign in with a unique username, how would I deal with the cases like "Mike" and "mike"?  I don't want to separate usernames, both as mike.  Is there a way to make all the entries entered into the database lowercase?  Or some way to solve this issue?

have a look here at <a href="http://uk3.php.net/strtolower"> strtolower() </a>

<?php

$str = "Mary Had A Little Lamb and She LOVED It So";

$str = strtolower($str);

echo $str; // Prints mary had a little lamb and she loved it so

?>

This function, as it states, will make all the letters in a string, lowercase. You can then check the database for the existing username - in lowercase form.

Hope this helps.
