Basically I've got a working drop-down menu php/mysql script running using the internet as my guide. But one thing I don't really understand is the significance of the period in
$options.
$sql = "SELECT DISTINCT artist FROM hits ORDER BY artist";
$result = mysql_query($sql);
while ($row=mysql_fetch_array($result)) {
$artist=$row["artist"];
$options.="<option>$artist</option>";
}
?>
I understand the rest etc but its just that one part that doesn't make sense to me, what does the "." do?!
Thanks
