    <p>I am trying to use PHP's json_decode function to get a particular value from a json object. Sample code below:</p> <pre><code>foreach ($streams as &amp;$i) { $chan = "http://api.justin.tv/api/stream/list.json?channel=" . $i; $json = file_get_contents($chan); //Turns the gathered file information into a string for searching purposes. echo $json . " End of json variable.&lt;br&gt;"; $exist = strpos($json, 'name'); // Search the file/json object for the name attribute if($exist) { // Check to see if a name existed and if so add it to the live streams and get the image. echo " &lt;a href=\"http://justin.tv/" . $i . "\"&gt;" . $i . "&lt;/a&gt; &lt;br&gt;"; $liveStreams[$count] = $i; $json_information = json_decode($json,true); $image[$count] = $json_information[0]['channel']['image_url_large']; echo "Image link should appear: " . $image[count]; $count++; } } </code></pre> <p>So What I am trying to do with this is first and foremost gather which streams are active from a list provided earlier in the code. Second, if the stream is live, display a link to a page for it to be viewed(currently the justin.tv stream itself). What currently works is only the live streams will appear with links to them. What I need is to figure out why after decoding I cannot access the image_url_large variable. This is going to be a thumbnail view of the stream eventually.</p> <p>I have looked at various places for what should have worked and even on stackoverflow I saw the following thread:</p> <p><a href="https://stackoverflow.com/questions/1270016/json-decode-in-php">json decode in php</a></p> <p>I tried doing it like nickf's answer and it still isn't working. Any help would be greatly appreciated as well as staying within the array style instead of going into objects.</p>

    1. COvar_dump($json_information) - what do you get?

    2. COit should be `if ($exist !== FALSE)`, to be 'correct'. strpos can return 0 if what you're looking for is right at the start of the string, which would otherwise be interpreted as false.

    3. COI am working inconjunction with another person. He is the one that gave me the code for the exists and this sit eh way that he wanted to do it. If you want a sample of the code returned, enter: http://api.justin.tv/api/stream/list.json?channel=beastyqt The name is never first according to the API so I doubt that will be an issue.

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.
