unable to get json data from server

Question

My server side code is:

$bus = array(
       'meaning' => $name
       );

$jsonstring = json_encode($bus);
echo $_GET['callback'].'(' . $jsonstring. ')';

the value displayed on the screen is correct - ?word=heart({"meaning":"heart"}) but when I am reading it with following code its printing the value of meaning as 11200665987893779229_1460521505942

$(document).ready(function(){
    $.getJSON('http://mydomain?callback=?','word=heart',function(res){
     document.getElementById('print').innerText=''+res.meaning;
    });
});

but when I do this:

$bus = array(
       'meaning' => 'heart'
       );

it's printing the correct value i.e heart

I am not getting why this is happening and how to get the correct value (I am accessing data from my different domain).

$name = substr($_GET['callback'],6); i have printed its value and it's heart — Gurpreet Singh, Apr 13 '16 at 04:36
problem may be in this line `echo $_GET['callback'] . '(' . $jsonstring. ')'; ` did you think its correct — uzaif, Apr 13 '16 at 04:40
it is correct , it's printing this ?word=heart({"meaning":"heart"}) as i mentioned everything is working fine but if i use a variable lie $name="heart" instead of using "heart" directly it's printing some code on client side but result is still printed correctly by echoing on screen on server side — Gurpreet Singh, Apr 13 '16 at 04:40
`$bus = array(); $bus['meaning'] = $name` and then access it — uzaif, Apr 13 '16 at 04:44
i am on a free hosting site without command line can you show me a working example which returns a user defined variable as json — Gurpreet Singh, Apr 13 '16 at 04:50
try to console.log(res) and see if it return json object or not? — uzaif, Apr 13 '16 at 05:01
it's printing this Object {meaning: "112003844644431846105_1460523934371"} — Gurpreet Singh, Apr 13 '16 at 05:05
i have echoed it and "heart" is printed then i make that echo statement a comment — Gurpreet Singh, Apr 13 '16 at 05:11
From what I can see the issue is with the javascript call, `res` is not returning what you're expecting. Since this is a cross-domain call I would expected that the return url would look something like _callback? 11200665987893779229_1460521505942_.

this is being returned JQuery1120030792344501622915_1460524412063({meaning: "1120030792344501622915_1460524412063"}) meaning : "1120030792344501622915_1460524412063" — Gurpreet Singh, Apr 13 '16 at 05:20

JSON.parse() converts any JSON String passed into the function, to a JSON Object.

$(document).ready(function(){
$.getJSON('http://mydomain?callback=?','word=heart',function(res){
obj = JSON.parse(res);
 document.getElementById('print').innerText=''+obj.meaning;
});

});
