   if (!$mysql_connect)  die("unable to connect to database: " . mysql_error());

  @mysql_select_db($db_name) or die( "Unable to select database");

 $result = mysql_query($query);
 $response = array();
 if($result === FALSE)
{
   die(mysql_error()); // TODO: better error handling
}
while($row=mysql_fetch_array($result))
       {  


    $date = "Date.UTC(".$row ['date'].")";
    $frequency =$row['frequency'];
    $response[] = array ($date,$frequency);


     }

 JSONArray jArray;
  String s = jArray.toString(); 

     mysql_close($mysql_connect);

json_encode：

<?php
$json_string = json_encode($your_array);

你甚至费心去谷歌这个吗？
