Question

If there is an error function mysql_result then it returns 0?

I looked everywhere but i could not find an answer ….

<?php
    include "config.php";
    $result = mysql_query("SELECT `price` FROM `prices` where bin = 1 limit 0,10" ) ;
    $i=0;
    $d=0;
    while($i!=10){
        $d=$d+mysql_result($result, $i)or die($d);  
        $i++;
    }
?>

its returns 7 errors …

Try this:

<?php
    include "config.php";
    $result = mysql_query("SELECT `price` FROM `prices` where bin = 1 limit 0,10" ) ;
    $i=0;
    $rows = mysql_num_rows($result);
    $d=0;
    while($i < $rows && $tmp=mysql_result($result, $i++)){
        $d+=$tmp;
    }
?>
