I'm using file() to get the contents of a remote page in my script but
I cannot find any information regarding how I could *gracefully*
handle a broken network connection or even a time-out (slow
connection).

Is there a way?

---
Example:
$menu = file('http://www.remotesite.org/mypage.html');
foreach ($menu as $line_num => $line) {
echo $line."\n";
}

theoretically, you could use a stream context and set a notification
handler, however, i was unable to get notifications when using this code:

function httpStreamNotificationHandler($notification_code, $severity,
$message, $message_code, $bytes_transferred, $bytes_max) {
echo __FUNCTION__ . PHP_EOL;
var_dump(func_get_args());
}
$options = array('http' =>
array('method' => 'GET',
'timeout' => 3
)
);

$streamContext = stream_context_create($options);
if(stream_context_set_params($streamContext, array('notification',
'httpStreamNotificationHandler'))) {
echo 'stream context parameters set, loading remote resource..' .
PHP_EOL;
// load remote resource
$theFile = file('http://www.remotesite.org/mypage.html', null,
$streamContext);
var_dump($theFile);
} else {
echo 'couldnt set context parameters' . PHP_EOL;
}

you might also get something out of the timeout option, which i set in the
code above,
but ive not verified its working correctly either.
also, you might try curl.

I'm not exactly sure what you are trying to accomplish or what sort of
access you have to the server, but if it were me I wouldn't rely on a
remote connection in real time. I would have a cron job that
periodically updated the results that I am expecting so that reads on
your site are very fast. Like I said though I'm not sure what you're
using this for so I cannot say whether or not it is okay for you to
cache this data locally for 5 minutes or even 1 day.

If you can cache it but cannot run cron jobs, then just write the
return buffer to a file and hold that for as long as possible checking
the last time it was wrote to see if it needs a refresh.

Use http://php.net/set_error_handler

You can change the timeout with set_ini() right before the file() call.

If $menu === false, then it failed.
