When sending the request from the jQuery script to the specified PHP file, nothing is returned, nothing is appended to the html file. Here's the URL of the page:

localhost/basket/newstext.html?url=basket-planet.com/ru/news/9235

newstext.html:

<head>
<script src="js/newstext.js"></script>
</head>
<body>
<div data-role="page" id="newstext">
<div data-role="content">
<div id="textcontent"></div>
</div>
</div>
</body>

newstext.js:

var serviceURL = "http://localhost/basket/services/";
$('#newstext').bind('pageshow', function(event) {
var url = getUrlVars()["url"];
$.getJSON(serviceURL + 'getnewstext.php?url='+url, displayNewsText);
});

function displayNewsText(data){
var newstext = data.item;
console.log(newstext);
$('#textcontent').text(newstext);
$('#textcontent').trigger('create');
}

function getUrlVars(){
//it displays in the alert perfectly, shortening the message here
}

getnewstext.php:

<?php
include_once ('simple_html_dom.php');
$url = $_GET['url'];
$html = file_get_html(''.$url.'');

$article = $html->find('div[class=newsItem]');
$a = str_get_html(implode("\n", (array)$article));
//parse the article
header("Content-type: application/json");
echo '{"item":'. json_encode($a) .'}';
?>

I think my problem is how I'm encoding the $a variable in the PHP script. The $a variable contains html tags of all kind...how can I append it in the html file?
