<?phpinclude ("configaz.php"); //數據庫連接在另一個文件內，這里就不弄了    $sql="select sid,sname,sPRice,count(sprice) as pricenum from shangpin group by sname";    $query=MySQL_query($sql);    $row=mysql_fetch_array($query);    while($row=mysql_fetch_array($query)){    $pricenum=$row['pricenum'];    $sname=$row['sname'];    }     echo $str .= "['".$sname."',".$pricenum."],";//拼接字符串，按照jqChart要求的字符串格式，當然用數組更好，可惜不怎么會

肯定還有更好的方法 只是我剛開始學，慢慢摸索
