Darn, I left out an important function, the fread(). Code snip should be:
$fp= fopen("http://www.anything.com/foo.html, 'rb');
if(!fp) {do something different}
stream_set_timeout($fp, 2);
$contents= fread($fp, 200000);
$status= stream_get_meta_data($fp);
if($status[timed_out] {do something};
It appears to me there is a basic logic problem. The script must get past the
fread() function before it gets to the stream_get_meta_data($fp). But, it hangs
up on fread() and the script times out.
