    <p>Here is the deal. I have a requirement to monitor certain password-protected webpage for changes and play sound alarm when size of the page is different from what I know (i.e. it was modified). Here is the chunk of code that i've come up with.</p> <pre><code>&lt;?php $e = curl_init(); curl_setopt($e, CURLOPT_URL, 'http://example.com/Account/LogOn'); curl_setopt($e, CURLOPT_POST, 1); curl_setopt($e, CURLOPT_POSTFIELDS, 'UserName=xxx@example.com&amp;Password=password'); curl_setopt($e, CURLOPT_COOKIEJAR, 'cookie.txt'); curl_setopt($e, CURLOPT_REFERER, 'http://example.com'); curl_setopt($e, CURLOPT_RETURNTRANSFER, 1); curl_exec($e); $sizevalue = 2399; do { curl_setopt($e, CURLOPT_URL, 'http://example.com/panel.php'); $content = curl_exec($e); $numberofchars = strlen($content); sleep(15); } while ($numberofchars = $sizevalue); curl_close($e); echo ' &lt;audio controls="controls" autoplay="autoplay"&gt; &lt;source src="/path/to/your/audio.mp3" type="audio/mp3"&gt; &lt;source src="/path/to/your/audio.ogg" type="audio/ogg"&gt; &lt;embed src="/path/to/your/audio.mp3"&gt; &lt;/audio&gt;'; php?&gt; </code></pre> <p><strong>Problem 1</strong>. Correct me if I am wrong, but as I understand, instead of connecting server, posting username and password only once, leaving the connection alive and using that auth key from <code>cookie.txt</code> for later actions it constantly sends the username and password to the login form for every turn of the cycle. How do I fix this?</p> <p><strong>Problem 2</strong>. I need the script to give me some temporary status because at the moment if certain condition is not met it basically turns into infinite loop and server hosting the script gives me timeout error.</p> <p><strong>Problem 3</strong>. What would be the simplest way to implement sound alarm? OGG file playback? Youtube redirection?</p>

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.
