PHP socket does not handle the data stream, how to avoid (as if blocked)

The PHP socket does not handle the data stream, how to handle it (as if it were blocked)
Requirements: PHP accepts a hardware to send data to port 8888, if received, should socket_send function return "\xfa\x01\x01\xff\xaa\xaa\x00\x01\x00\x00\x00\x00\x00\x01", After the hardware receives the data sent by the Socket_send, it will "drip" a sound, but the problem arises, a hardware is OK, but when multiple hardware at the same time to connect and send data at the same time, the hardware can not be a continuous response (that is, the "drip" sound), that is, can be continuously issued "drip" sound, it is , about a few seconds later, and began to respond, after a while, a few connections on the hardware is the case, I have used the non-blocking mode, or this, to solve the problem, the following post code

PHP Code

   = $MAX _users) {$reject = "Server full.                                   Try again later.\n ";                }//Put the current client connection as Socket_select select $connections [$i] = $newconn;                               Enter the connection resource cache container $writefds [$i] = $newconn;                Not connected properly if ($reject) {$close [$i] = true;                                  } else {echo "Welcome to the PHP Chat server!\n";                }//initializes the cache container for the current connection read content $input [$i] = "";            Continue            }//Client connection $i = (int) $rfd;            Read $tmp = @socket_read ($RFD, Php_normal_read);                if (! $tmp) {//Cannot read content print "Connection closed on socket $i \ n";            Close ($i);    Continue            } $input [$i]. = $tmp;            $tmp = substr ($input [$i],-1);                /*if ($tmp! = "\ r" && $tmp! = "\ n") {//no end of line, more data coming            Continue            }*/$line = Trim ($input [$i]);            $input [$i] = ""; Echo ' Client >> '. $line.
