[WHOOPS! sorry had the key point reversed in my text. ] I have been trying to understand how to use stream_set_timeout when calling a remote http page and put together the following code snippets. The first one is a simple test file "test.php" that is called as an html webpage. The key I found is the "stream_set_blocking($fp, TRUE )". If "FALSE", then $status['timed_out'] seems to not have any practical effect. "TRUE" [PHP default] works. Note, I have two timeouts, stream and monitor. I need both in my application. <?php echo $html_stuff\n; //the html header, etc. ob_flush(); //makes it echo immediately $delay= 20; //tweak this, seconds $report = "<div>Test started at: " . date("H:i:s")</div>\n"; $report .= "<div>Started delay= $delay)</div>\n"; echo($report); ob_flush(); $i=1; $start_time= time(); while($i <= 10){ $diff= time()-$start_time; $msg = $i . " at " . $diff; echo "$msg \n"; sleep($delay); $i= $i+1; } // end while $report = "Finished\n"; $report .= " </body>\n</html>"; echo($report); ?> The second code block calls test.php with the usual "fopen()" <?php $fp= fopen("http://URL/.../test.php", 'rb'); $query_timeout= 4; //tweek this $monitor_time_sec= 120; //master timeout stream_set_blocking($fp, FALSE ); //THIS IS IMPORTANT stream_set_timeout($fp, $query_timeout); $status = socket_get_status($fp); // fetch data from test.php while (!feof($fp) && !$status['timed_out']) { $chunk = fread($fp, 10000); $length = strlen($chunk); $html_str .= $chunk; $diff = time() - $start_time; $tm = $status['timed_out']; echo "<div>At $diff seconds >> $length bytes read, Status[timed out]: ($tm)</div>"; ob_flush(); if ($diff > $monitor_time_sec) { $pq_array['monitor_timed_out'] = true; break; } //end if sleep(2); $status = socket_get_status($fp); } //end while, fetching data fclose($fp); $pq_array['connection_timed_out'] = ($status['timed_out'])? true : false; print_r($pq_array); echo $html_str; //or whatever. ?>

stream_set_timeout() is not suitable for such files as UNIX-devices (/dev/...), i suggest to use select() instead with desirable timeout value - that works well.

If you are using fsockopen() to create a connection, first going to write into the stream and then waiting for the reply (e.g. simulating HTTP request with some extra headers), then stream_set_timeout() must be set only after the write - if it is before write, it has no effect on the read timeout :-( Noticed at least on PHP/4.3.10

I have found that in order to actually stop the socket from timing out the script, you must call stream_get_meta_data and check for a timeout within the loop reading from the socket. Example: <?php $sock = fsockopen($host, 80, $errno, $errstr, 30); if(!$sock){ echo "Unable to get server status"; }else{ $out = "GET /server.php HTTP/1.1\r\n"; $out .= "Host: $host\r\n"; $out .= "Connection: Close\r\n\r\n"; fwrite($sock, $out); stream_set_blocking($fp, FALSE ); stream_set_timeout($sock, $timeout); $info = stream_get_meta_data($sock); while (!feof($sock) && !$info['timed_out']) { $file .= fgets($sock, 4096); $info = stream_get_meta_data($sock); } fclose($sock); ?>

I have found it required to add "stream_set_blocking($fp, FALSE )" prior to any fgets(), fread(), etc. to prevent the code from hanging up when remote files are called and the response is slow.

Here is a working example for loops: <?php // Timeout in seconds $timeout = 5; $fp = fsockopen("www.server.com", 80, $errno, $errstr, $timeout); if ($fp) { fwrite($fp, "GET /file.php HTTP/1.0\r\n"); fwrite($fp, "Host: www.server.com\r\n"); fwrite($fp, "Connection: Close\r\n\r\n"); stream_set_blocking($fp, TRUE); stream_set_timeout($fp,$timeout); $info = stream_get_meta_data($fp); while ((!feof($fp)) && (!$info['timed_out'])) { $data .= fgets($fp, 4096); $info = stream_get_meta_data($fp); ob_flush; flush(); } if ($info['timed_out']) { echo "Connection Timed Out!"; } else { echo $data; } } ?>
