The script will not block and will continue executing like normal, reading from the socket is instant and never buffers, so basically, you have a socket that can recive and process data extreamly fast, but is not able to write back to the stream at the same speed. Reproduce code: --------------- <?php $s = fsockopen("localhost",23); stream_set_timeout($s,0,95000); stream_set_blocking($s,false); stream_set_write_buffer($s,0); $i = 0; while ($i < 1000) { $i++; if (feof($s)) break; $in=trim(fgets($s,4096)); if ($in != "") { usleep(5000); // do some processing here } fwrite($s,"hello $i\r\n"); } ?> Expected result: ---------------- i expect it to write "hello #\r\n" where # is 1-1000 to the socket very fast (at least once every 0.1 seconds) Actual result: -------------- it will write around 10 lines to the socket very quickly, then will start to buffer at around 1 line per second, which in the case where you need results to come back very fast, it makes it quite annoying to deal with ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=36384&edit=1
