That's exactly what stream_set_timeout does, *IF* more than 2 seconds goes
by with *NO* data coming through.

If you want to put a cap on the total time spent, regardless of the file
size, then do more like:

>> $fp= fopen("http://www.anything.com/foo.html, 'rb');
>> if(!fp) {do something different}
>>
>> stream_set_timeout($fp, 2);
>>
// >> $status= stream_get_meta_data($fp);

$start = time();
while (!feof($fp)){
$data = fread($fp, 10000); //10K chunks, change to suit
if (time() - $start > 10){
die("That's too slow!");
}
}

Please review this exact same issue in the archives from the past week or
two.
