Body
Aside from the silly use of strpos(), which you seem to claim was someone else's idea, it seems like you just need to carefully debug. Do something like this: <pre><code>$data = json_decode($json,true); echo "<PRE>"; var_dump($data); die(); </code></pre> Now you can see the data structure the API is giving you. Look at the structure of the array. Notice, for instance, that <code>$data['image_url_large']</code> does not exist. There is, however, <code>$data[0]['channel']['image_url_large']</code>! Notice also that instead of the silly strpos() call, which will give false positives if the string "name" exists anywhere in the json-string, you could do something like: <pre><code>$exists = ! empty($data[0]['name']); </code></pre> EDIT Here's some code that will hopefully help you on your way: <pre><code> <?php //if you don't do this, you're flying blind. ini_set('display_errors',1); error_reporting(E_ALL); //list.json is a copy of the data from the URL you posted. $json = file_get_contents('./list.json'); //decode the data $data = json_decode($json,true); //uncomment this if you're not sure of what the json's structure is. #echo "<PRE>";var_dump($data);die(); //check for the existence of a "name" key in the first item. $exist = ! empty($data[0]['name']); echo "Exist?:"; if ($exist) { echo " yes\n"; }else{ echo " no\n"; } //output the image url: echo $data[0]['channel']['image_url_large']; //say goodbye die("\n\nAll done.\n"); </code></pre> OUTPUT: <pre><code>$ php test.php Exist?: yes http://static-cdn.jtvnw.net/jtv_user_pictures/beastyqt-profile_image-c5b72ccf47b74ed2-300x300.jpeg All done. </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
