    <p>I would use <a href="http://ch.php.net/manual/en/function.sscanf.php" rel="nofollow">sscanf</a></p> <p>Untested example:</p> <pre><code>list($node_id, $pdf_id) = sscanf($url, "node/%d/pdf/%d"); </code></pre> <p><code>$node_id</code> contains the node id, <code>$pdf_id</code> contains the pdf id. According to your comment: Yes, you can output it with e.g. <code>echo $pdf_id;</code>.</p> <p>If you need them both in an array, you can remove the <code>list()</code> method, doing it like this: </p> <p><code>$ids = sscanf($url, "node/%d/pdf/%d");</code>. </p> <p>This returns an array with both node and pdf id in <code>$ids</code>.</p> <p>Finally, if you just need the pdf id, you could do </p> <p><code>$id = sscanf($url, "node/95/pdf/%d");</code>.</p> <p>I just showed how to fetch both because I assumed you may need both numbers from your url.</p> <p><strong>Edit</strong><br> seeing all the other answers after posting my solution, I am wondering why everyone is solving this with multiple functions when there is a function available that does exactly what he needs: parsing a string according to a format. This also leads to less sql-injection prone code IMHO. And it doesn't break something when the url gets extended or query strings are appended.</p> <p><strong>Edit 2</strong> <code>list($node_id, $sub, $sub_id) = sscanf($url, "node/%d/%[^/]/%d");</code> will get you the "pdf" and it's id separate instead of "node/%d/%s/%d". This is because char <code>/</code> is also matched by <code>%s</code>. Using <code>%[^/]</code> matches everything except the forward slash.</p>

    1. COi don't quite get your code. How will get the pdf_id? echo $pdf_id? Sorry if i'm really slow on this.

    2. COin this example, sscanf returns an array. `%d` means "digits". so sscanf takes your url, and assumes there is `node/<any_digits>/pdf/<any_digits>`. the digits parts returned by sscanf as array. using list() saves them in separate variables, which could be convenient and because I thought you may also need the node id. I updated the answer to provide more examples.

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.
