Answer 1

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;
    }
?>

In my opinion, you shouldn't use mysql_result. It is slower than the other methods.

Try mysql_fetch_array()

prototype:

while ($row =
    mysql_fetch_array ($result)){

echo (whatever you want depending upon the index);

}

or you can also return it as an array.

尝试删除第7行的die（$ d）并再次检查。
