If it is a basic theory of the procedure I can break it down for you.

Query the database and count what is returned.
If you get no returned records you did not find what you were looking for... Look at the contents of the $query variable.

Code:
<?php

$link = mysql_connect("localhost", "mysql_user", "mysql_password");
mysql_select_db("database", $link);

$query = "select count(*) from users_table where username='johndoe';";

$result = mysql_query($query, $link);

print mysql_num_rows($result) ? 'Found It' : 'I found nothing';

?>
