I have a ajax connection to my json.php file and its not working... do you have any idea what is going on?
is it my $output variable is it not convertible to json can it be my ajax?!
any help will be greatly appreciated. PS: when i click on a city that does not exist.. it does output the $output variable.When i click on a city that doe exist I get nothing.
It`s killing me.
var_dump($output) {if it is not encoded} is:

    array (size=1)

  0 => 

    array (size=4)

      0 => 

        object(SimpleXMLElement)[9]

      1 => 

        object(SimpleXMLElement)[8]

      2 => 

        object(SimpleXMLElement)[7]

      3 => 

        object(SimpleXMLElement)[10]

json.php file:

<?php



if(isset($_POST['city'])){

    $city = $_POST['city']; //checks if variable city is set if not it will be set as default 

    var_dump($city); 

}else{

    $city = 'New York';





}

//loads data as simple xml

$result = "http://api.wunderground.com/api/KEY/geolookup/conditions/q/ro/$city.xml";

$xml = simplexml_load_file($result);

#echo htmlspecialchars($result, ENT_QUOTES, 'UTF-8');

$place = $xml->location->city; //gets the city name

#var_dump($place);

if(!empty($place)){ //checks if city exits

  foreach($xml->current_observation as $item){

    $current = (string)$item->weather;

    $temperature = (string)$item->temp_c;

    $time = (string)$item->local_time_rfc822;

    $wind = (string)$item->wind_string;

    $humidity = (string)$item->relative_humidity;

    $output = array($time, $temperature, $current, $wind); 



}



    }

}else{

    $output = 'No results found, please try a different city.';  //if variable $place is empty it will print this

}



header('Content-Type: application/json; charset=utf-8');

echo json_encode(array('data' => $output),true);

?>

And jQuery file:

 $(document).ready(function() {

    $('li').click(function(){

            var city = $(this).text(); //get the li content as variable city

            $.ajax({



                type : 'POST',      //sending data method

                url : 'json.php',

                data : {city:city}, //data to be sent

                dataType: 'json',

                success : function(data){

                $("#result").html(data);

            }

            });



    });

});

EDIT 1:
I have updated my code in such a way that my output is json encoded and equal to

{"data":[["Thu, 24 Sep 2015 02:00:58 +0300","19.3","Clear","From the West at 1.6 MPH Gusting to 2.5 MPH"]]}

I think the problem now is in my AJAX(I am a new user of jQuery) I get no info printed when I Click on a city.

Many Times it occurs when our content of the array is not Encoded. Generally we use UTF-8 Encoding.

So, To Solve this issue you need to add this,

mysqli_set_charset($con, 'utf8');

Just after the connection.

Take a look at the following tutorial: https://lostechies.com/seanbiefeld/2011/10/21/simple-xml-to-json-with-php/

You'll do str_replace and trim then encode the data for the web.
