Question

I am grabbing entries from a database and displaying them on my web page like so:

$query = mysql_query("SELECT * FROM posts order by id desc") or die(mysql_error()); 
if (!$query) {
    die('MySQL error'); 
} else {
    while($row = mysql_fetch_array($query)):
    // HTML stuff with <?php echo $row['title']; ?>
endwhile; }

How can I write a if statement to echo “Nothing Found” if there are no entries to get? So basically, if the query does its thing and finds nothing, how can I echo some sort of “error message”?

You can use:

if (mysql_num_rows($query) > 0) {
    // while here
} else {
    // error output here
}
