Widget to Show uCash Leaders

[ZacFields]

Hi All,

I've written some code (my first ever SQL/PHP code write, actually) that simply takes each users' Ucash balance and displays them in descending order, stopping at the 20th ranked person.

Running this code directly from a PHP file on my site works great, but I'm trying to get it into a CMS widget and I'm having a little trouble with the concept of using the $output variable rather than echo. Obviously just changing every instance of "echo" to "$output" doesn't work, what am I doing wrong? Here is the code raw:

$user=$_POST['user'];
$username=$_POST['username'];
$ucash=$_POST['ucash'];



$query = "SELECT * FROM `user` ORDER BY `user`.`ucash` DESC";
$result=mysql_query($query);
$num="20";


mysql_close();


echo "<b>Vcash Leaderboard</center></b><br><br>";
?>
<table border=0>
<tr><td><b>Username</b></td><td><b>vCash</b></td></tr>
<?
$i=0;
while ($i < $num) {


$rank=$i+1;

$username=mysql_result($result,$i,"username");
$ucash=mysql_result($result,$i,"ucash");
?>


<tr><td><?echo "$rank. $username"; ?> </td>
<td>$<?echo ROUND("$ucash"); ?> </td> </tr>




<?
$i++;
}


echo "</table>";

I'm feeling like it's something very basic that I'm missing. I'm proud of myself for doing the research that allowed me to write the code in the first place, but this $output stuff has thrown a curveball at me and I guess I'm not just understanding the concept.

Does anyone have any pointers on what I need to change in this code to make it work in the php direct execution widget? Essentially, when I paste this code in exactly as it is, it runs the script just fine... but it displays at the top of the page above the header.

Whoops, can somebody move this to the VB4 programming section? My apologies!
