php + jquery + ajax获取多个值

I am working with jQuery AJAX. Using an AJAX call I invoke a PHP page. By default it returns a single value to the success function of AJAX. However I want to retrieve multiple data individually. What can I do?

Here's the jQuery code with AJAX , which returns a single value:

function getTime(){
  $.ajax({
    type: "POST",
    url: "test.php",
    data: {
      fd: sdate,
      sd: edate
    },
    dataType: "text",
    success: function(msg) {
      $("#results").text(msg);
    }
  });
};

Test.php:

echo $days;
echo $hours;
echo $minutes;
echo $seconds;

    Typically to return multiple responses, the easiest way to do this is to return a json encoded array. Something like the following should work.

    echo json_encode( array(
        "days" => $days,
        "hours" => $hours,
        "minutes" => $minutes,
        "seconds" => $seconds
    ) );
    

    Since your ajax request has dataType: "text" you will need to parse the response to use it with JSON.parse(msg), however if you changed it to dataType: "json" you would not have to do this step as jQuery will try to auto parse it for you.
