    <blockquote> <p>How can I kill the session without having to go through that?</p> </blockquote> <p>The problem you're having <em>isn't</em> one that will be solved by killing the session.</p> <blockquote> <p>the hang arises from a blocking socket that never gets a message</p> </blockquote> <p>If you're using the default PHP session handler, that means that PHP is holding a lock on that file. No other PHP process is going to be able to manipulate the session as long as that lock exists. </p> <p>You have a few options here. </p> <p>First, consider <a href="http://us2.php.net/manual/en/function.session-set-save-handler.php" rel="nofollow">implementing you own session save routines</a>, which means you'd completely control whether or not there is any sort of lock on the session data. You can simply not include any locking at all, which will permit the running-but-hung PHP script to continue running in peaceful bliss. This is the most complex option.</p> <p>Second, are you sure that the long-running socket script needs to <em>write</em> session data? If not, you can simply end the session early and release the lock by calling <a href="http://us2.php.net/manual/en/function.session-write-close.php" rel="nofollow"><code>session_write_close</code></a>. This will release the lock, though it won't actually end the long-running script when the socket closes.</p> <p>Third, look at using socket timeouts in your long-running script. I'm not sure what exact method you're using to work with sockets here and have very little experience working with them in PHP, so I can't make a specific function recommendation.</p>

    1. COTo test your idea, I used a different file for the local socket--/tmp/sock1 instead of /tmp/sock. This file is new so php couldn't be holding a lock on it. It still hung, and in fact never got to that point--it hangs on the first line of login.php, which is session_start.

    2. CO@Matt, the lock is on the *session* file. `session_start` blocks waiting for the lock to release.

    3. CO@Charles Ok thanks, I am very new to php as is probably obvious at this point. :) session_write_close is also not working, only restarting the browser.

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.
