javascript - 将 JSON 数组中的字符串元素解析为整数

Question

 $con = new DBConnector();
 $sth =  $con->Query("SELECT medicinename as label, factor as data FROM medicine_master_tbl limit 4");
$rows = array();
while($r = mysql_fetch_assoc($sth)) {
         $rows[] = $r;
      }
echo json_encode($rows);

我的查询没有问题，但是返回值是..

[{"label":"rrp","data":"5"},{"label":"t","data":"34"},{"label":"tt","data":"4"},{"label":"nutrachin","data":"45"}]

我需要如下所示的 json 数组..

[{"label":"rrp","data":5},{"label":"t","data":34},{"label":"tt","data":4},{"label":"nutrachin","data":45}]

数据在这个数组中被视为字符串，我需要将其解析为整数..在此先感谢。

一个简单的。

while ($r = mysql_fetch_assoc($sth)) {
     $r["data"] = intval($r["data"]);
     $rows[] = $r;
}
