If that's your first use of $data then it's not necessary, but it's very
highly recommended to do something like:

$data = array();

mysql_query("SELECT ....");
while($rows .....)
{
$data[] = $rows;
}

That way you _know_ that $data is "clean" before you start doing
anything with it.

It's always a good idea to set any variables you're using to some value,
either "", array(), 0, or some default value, before you use them to
help keep the "bad guys" out of your scripts.
