Hello!

I am trying to echo the sum of the records in a table and it returns empty.

$query = "SELECT SUM(number) AS total FROM records";
            $result = mysql_query($query);
            echo 'the total is:';
            echo $total;

When I echo the query it appears as above, when I echo the $result it says Resource ID#5. When I echo $total is is empty. What am I doing wrong?

$result content is the resource id...you must fetch to get something

and also, php won´t guess what is $total...

try this:
<?php
$query = "SELECT SUM(number) AS total FROM records";
            $result = mysql_query($query);
            list($total) = mysql_fetch_row($result); // look at php.net to learn more about this
            echo 'the total is:';
            echo $total;
?>

Programming is like building your own universe...
But let me ask you something:
Your world... It´s cool? Or it sucks?

$query = "SELECT SUM(number) AS total FROM records";
            $result = mysql_query($query);
            $r = mysql_fetch_array($result);
            echo "total is: {$r['total']}";

Please, take the time and do some research and find out how much it would have cost you to get your help from a decent paid-for source. A "roll-of-the-dice" freelancer will charge you $5-$15/hr. A decent entry level freelancer will charge you around $15-30/hr. A professional will charge you anywhere from $50-$100/hr. An agency will charge anywhere from $100-$250/hr. Think about all this when soliciting for help here. Think about how much money you are making from the work you are asking for help on. No, we do not expect you to pay for the help given here, but donating a few bucks is a fraction of the cost of what you would have paid, shows your appreciation, helps motivate people to keep offering help without the pricetag, and helps make this a higher quality free-help community :)

$query = "SELECT SUM(number) AS total FROM records";
$result = mysql_query($query);
$row = mysql_fetch_assoc($result);
echo 'the total is:' . $row['total'];

Try that.

EDIT:... bah... beaten to it.
