Question

I have a php function that fetches and returns tweets data from twitter as simplexml object.I could get its contents by using php syntax. Here is php function

<?php

    function searchResults($q) {
    $host = "http://search.twitter.com/search.atom?q=" . urlencode( $q ) . "&rpp=100";
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $host);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);

    //Raw xml
    $result = curl_exec($ch);
    curl_close($ch);
    $xml = simplexml_load_string($result);
    return $xml;
    }            
?>

If I call it like

$xml = searchResults('xyz');

I could fetch its contents like

echo $xml->content.''.$xml->author->name;

Now I need to return it from php function in JSON format. Like

return json_encode($xml);

in spite of

return $xml;

So how do now I get same ‘content’ and ‘author->name’ etc contents from it in JSON format when I decode json.

Answer 1

It depends. If you’re accessing it back from PHP, there are two ways:

$obj = json_decode($json);
echo $obj->author->name;

or

$arr = json_decode($json, true);
echo $arr['author']['name'];

If you are accessing it using JavaScript, it should be:

alert(jsObject.author.name);
