Body
Error checking and handling is the programmer's friend. Check the return values of the initializing and executing cURL functions. <a href="http://php.net/manual/en/function.curl-error.php" rel="noreferrer"><code>curl_error()</code></a> and <a href="http://php.net/manual/en/function.curl-errno.php" rel="noreferrer"><code>curl_errno()</code></a> will contain further information in case of failure: <pre><code>try { $ch = curl_init(); // Check if initialization had gone wrong* if ($ch === false) { throw new Exception('failed to initialize'); } curl_setopt($ch, CURLOPT_URL, 'http://example.com/'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt(/* ... */); $content = curl_exec($ch); // Check the return value of curl_exec(), too if ($content === false) { throw new Exception(curl_error($ch), curl_errno($ch)); } /* Process $content here */ // Close curl handle curl_close($ch); } catch(Exception $e) { trigger_error(sprintf( 'Curl failed with error #%d: %s', $e->getCode(), $e->getMessage()), E_USER_ERROR); } </code></pre> <hr> * The <code>curl_init()</code> <a href="http://php.net/manual/en/function.curl-init.php" rel="noreferrer">manual</a> states: <blockquote> Returns a cURL handle on success, FALSE on errors. </blockquote> I've observed the function to return <code>FALSE</code> when you're using its <code>$url</code> parameter and the domain could not be resolved. If the parameter is unused, the function might never return <code>FALSE</code>. Always check it anyways, though, since the manual doesn't clearly state what "errors" actually are.

Guidance

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.
