Refer to the PHP stream to implement the server client model:

Server-side code:

1<?PHP2     //setting does not time out3     Set_time_limit(0);4 5     classSocketserver6     {7          Public function__construct ($port)8         {9             Global $errno,$errstr;Ten  One             $socket=Stream_socket_server(' tcp://127.0.0.1: '.$port,$errno,$errstr); A              while($conn=stream_socket_accept($socket,-1)) -             { -                 $buff= ' '; the                 $data= ' '; -                  -                 //read request data until \ r \ n Terminator is encountered -                  while(!Preg_match(' #\r\n# ',$buff)) +                 { -                     $buff=fread($conn, 1024); +                     $data.=Preg_replace(' #\r\n# ', ',$buff); A                 } at                 fwrite($conn,$data); -                 fclose($conn); -             } -             fclose($socket); -         } -     } in  -     NewSocketserver (1212);

Client

1<?PHP2     3     if(isset($argv[1]))4     {5         $msg=$argv[1];6         $socket=stream_socket_client(' tcp://127.0.0.1:1212 ',$errno,$errstr);7         if(!$socket)8         {9              die($errno.$errstr);Ten         } One         Else A         { -             //stream_set_blocking ($socket, 0); -              for($index= 0;$index< 3;$index++) the             { -                 fwrite($socket, "Client:$msg $index"); -                 Usleep(100000); -             } +             fwrite($socket, "\ r \ n"); -             $response=fread($socket, 1024); +             file_put_contents(' Log.txt ',Date("[H:i:s]", Time()).$response." \ n ",file_append); A             fclose($socket); at         } -     } -     Else -     { -          for($index= 0;$index< 3;$index++) -         { in             system(' PHP '.__file__."$index: Test "); -         } to}

Operating effect under CLI

After removing 13 lines of code that set the non-blocking mode, the client cannot write to the data returned by the server because of the usleep () delay.

Of course, the non-blocking mode can be used for maximum efficiency in cases where the client does not care about accepting the result.
