Note Submitter: pk at ritm dot ru ---- some info that can be useful (extension of previous message) if you want to use function fgets in your php tcp server, you should know that fgets is not adapted for packet tcp servers, ans stream_get_line is! difference here: For example, client want to send packet to server with total length of 100 bytes + ending delimiter \n (total=101b) Lets imagine that client will send 50 bytes of this packet because of its slow internet connection, wait 1-2 seconds, and then send data again. what will do server with function fgets? <?php // fgets server stream_set_timeout($s, 0, 0); stream_set_blocking($s, 0); sleep(10); // in this interval client will send 1st part of data var_dump( fgets($s, 2048) ); sleep(10); // now client will send 2nd part of data var_dump( fgets($s, 2048) ); // output will be: // string(50) "data here .." // string(51) "data here ... \n" ?> what will do server with function stream_get_line? <?php // stream_get_line server stream_set_timeout($s, 0, 0); stream_set_blocking($s, 0); sleep(10); // in this interval client will send 1st part of data var_dump( stream_get_line($s, 2048, "\n") ); sleep(10); // now client will send 2nd part of data var_dump( stream_get_line($s, 2048, "\n") ); // output will be: // bool(false) // string(100) "data here .." ?> what we have total? function stream_get_line is very smart and wait for full packet instead of fgets
