    <p>Can someone clarify what the APNs (Apple Push Notification) wants as far as how you query it?</p> <p>The docs say it starts sending as soon as the connection is made. Does this mean that I don't do an <code>fread()</code> on it?</p> <p>Here's my current code to try and read it. I did NOT put the <code>fread()</code> in a loop as I do not know what response indicates "no more records to read" and I didn't want an infinite loop on my server.</p> <pre><code>&lt;?php $apnsCert = 'HOHRO-prod.pem'; $streamContext = stream_context_create(); stream_context_set_option($streamContext, 'ssl', 'local_cert', $apnsCert); stream_context_set_option($streamContext, 'ssl', 'verify_peer', false); $apns = stream_socket_client('ssl://feedback.push.apple.com:2196', $error, $errorString, 60, STREAM_CLIENT_CONNECT, $streamContext); echo 'error=' . $error; echo 'errorString=' . $errorString; $result = fread($apns, 38); echo 'result=' . $result; fclose($apns); ?&gt; </code></pre> <p>So far all I am getting is a null reply. There are no errors so it is connecting.</p> <p>I don't know if the null reply means no data is there, or my <code>fread()</code> is the wrong way to do it.</p> <p>Thanks</p>

    1. COToday I found that fread() won't work because APNs feedback sends garbage data until the actual feedback. This causes fread to fail, because it's reading null/empty data. As gw1921 mentions below, you must loop on feof() until strlen(fread($apns, 38)). From that point on, you'll have valid feedback. Then, unpack the data as Nick B below has suggested. (Another nasty gotcha: the uninstalled app won't generate feedback unless you have another app on the device with the same aps-environment. So you need 2 push-enabled sandbox apps on your device for the uninstalled one to populate feedback.)

    2. COEven I have a similar code and I too get null from fread. Not sure whether my code is really working and APNS is sending out a NULL reply or just something is missing. I'm sure my connection to APNS is successful. I had installed my application on some 5-10 devices and send couple of alerts and then uninstalled the application from few and started sending the alerts again so that APNS feedback server would let us know it failed to deliver on few devices. I haven't got anything other than blank in fread() :-( If you have done something different and got it working please do let me know.

    3. COHave you used "pushutil"? Once you figure it out, it's a faster way to check the feedback server. It's a Mac OS X utility that you compile and then run from the Unix command line. Google Erica Sadun - it's on her site under Push.

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.
