Question

I am getting NULL for all my JSON data here is my code

$jsons1 = file_get_contents($api_url); // returns JSON
        $jsons=json_decode($jsons1);

        foreach ($jsons as $json)
        {
        echo "\n";
        echo "<ul>";
        echo "<li>";
        echo "\nTitle : ".$json->title."\n";
        echo "\nContent: ".$json->content."\n";
        echo "</li>";
        echo "</ul>";
        }

I am unable to fetch it like $json->title, Am i missing something?

The output is

 - Title : Content: 

Please help in this regard

here is output of $jsons1 variable

{"results":[{"title": "Temp, Russia - Wikipedia, the free encyclopedia","kwic": "Coordinates : 52°03′N 39°44′E  /  52.05°N 39.733°E  / 52.05; 39.733  tenmp ( Russian : УÑмань ) is a town and the administrative center of ...","content": "","url": "http://en.wikipedia.org/wiki/sdfds,_Russia","iurl": "","domain": "en.wikipedia.org","author": "","news": false,"votes": "1","date": 1357744155518,"related":[]}],"query": "tenp","suggestions":[],"count":96,"start":1,"length":10,"time": "412"}

Answer 1

Try as

$j = '{"results":[{"title": "Temp, Russia - Wikipedia, the free encyclopedia","kwic": "Coordinates : 52°03′N 39°44′E  /  52.05°N 39.733°E  / 52.05; 39.733  tenmp ( Russian : УÑмань ) is a town and the administrative center of ...","content": "","url": "http://en.wikipedia.org/wiki/sdfds,_Russia","iurl": "","domain": "en.wikipedia.org","author": "","news": false,"votes": "1","date": 1357744155518,"related":[]}],"query": "tenp","suggestions":[],"count":96,"start":1,"length":10,"time": "412"}';

$data = json_decode($j,true);

foreach ($data["results"] as $key=>$val){
    echo "\n";
    echo "<ul>";
    echo "<li>";
    echo "\nTitle : ".$val["title"]."\n";
    echo "\nContent: ".$val["content"]."\n";
    echo "</li>";
    echo "</ul>";
}

Right now there is only one data in results element so looping is better if there are more.

You have object results containing your datas..

So you have just to fix your Foreach statement ..>

    foreach ($jsons->results as $json) { ... }
