PHP code sharing: Open the multi-process PHP login Interface code PHP code codes PHP Registration page code

Here to share a process of opening the PHP code, not more explanations, are in the comments.

The example in this article describes how PHP opens a multi-process approach. Share to everyone for your reference. The implementation method is as follows:

  Externally connected socket global $ServerSocket, $RemoteSocket, $IP, $Port; $ServerSocket = $ConnectedServerSocket; DECLARE (ticks = 1); This line must be added, otherwise there is no way to set the message function. Set Message function if (!pcntl_signal (SIGTERM, "childsignalfunction")) return; if (!pcntl_signal (SIGTRAP, "childsignalfunction")) return;//establish a connector to the VNC socket $RemoteSocket =socket_create (af_inet, SOCK_STREAM,SOL_TCP);//Connect to the internal VNC @ $RemoteC if (! $RemoteConnected) return; No connection to VNC end//The socket is set to Nonblock to avoid the program being blocked if (!socket_set_nonblock ($RemoteSocket)) return; if (!socket_set_nonblock ($ServerSocket)) return;   while (true) {//This side we use pooling way to obtain information $NoRecvData =false; This variable is used to determine if the external connection has read the information $NoRemoteRecvData =false;//this variable to determine if the VNC connection has read the information @ $RecvData =socket_read ($ServerSocket, 4096, Php_binary_read);//read 4096 bytes from external connections @ $RemoteRecvData =socket_read ($RemoteSocket, 4096,php_binary_read);//   Read 4096 bytes's information from the VNC connection ($RemoteRecvData = = =) {//vnc, the end cola echo "Remote Connection close\n";     Return } if ($RemoteRecvData ===false) {/* Since we are using NONBLOBK mode here is VNThe C connection does not have the information to read */$NoRemoteRecvData =true;//Remove the last Errror socket_clear_error ($RemoteSocket);   } if ($RecvData = = =) {//external connection interrupted, the end bundle cola echo "Client Connection close\n";  Return if ($RecvData ===false) {/* Since we are using NONBLOBK mode this is where the external connection does not have the information to read */$NoRecvData =true;//erase last Errror socket_clear_e  Rror ($ServerSocket); if ($NoRecvData && $NoRemoteRecvData) {//If external connections and VNC connections are not available to read,//Let the program sleep for 0.1 seconds to avoid long-term CPU usleep (100000);  /After waking up, continue to make pooling movements to read the socket continue; }//recv Data if (! $NoRecvData) {//external connection read to data while (true) {////external connection read information, transferred to VNC connection @ $WriteLen =socket_write ($RemoteS    Ocket, $RecvData);     if ($WriteLen ===false) {//due to the problem of Internet transport, currently can not be written into the information//sleep for 0.1 seconds before continuing to try.     Usleep (100000);    Continue     } if ($WriteLen ===0) {//Remote connection is interrupted, the program should end up with the echo "Remote Write Connection close\n";    Return    The information}//from the external connection has been completely sent to the VNC connection, which interrupts this loop.   if ($WriteLen ==strlen ($RecvData)) break;//If the information can be sent in a few times after the delivery, until all the information is sent out for $RecvData =substr ($RecvData, $WriteLen); }} if (! $NoRemoteREcvdata) {//This is the information that is read from the VNC connection, and then sent back to the external connection//the principle is almost no longer baggage (true) {@ $WriteLen =socket_write ($ServerSocket, $RemoteRec    VData);     if ($WriteLen ===false) {usleep (100000);    Continue     } if ($WriteLen ===0) {echo "Remote Write Connection close\n";    Return    } if ($WriteLen ==strlen ($RemoteRecvData)) break;   $RemoteRecvData =substr ($RemoteRecvData, $WriteLen); }}}} function Destroysocket () {//used to close the opened socket global$serversocket, $RemoteSocket; if ($RemoteSocket) {//If the VNC connection has been opened  The socket must be shutdown before the close socket is not known that you have closed the connection @socket_shutdown ($RemoteSocket, 2);    Socket_clear_error ($RemoteSocket);//Close Socket Socket_close ($RemoteSocket); }//close the external connection @socket_shutdown ($ServerSocket, 2); Socket_clear_error ($ServerSocket); Socket_close ($ServerSocket); }//here is the beginning of the whole program, and the program starts from here.//This first performs a fork $PID =pcntl_fork (); if ($PID ==-1) die ("Could not fork");//If $pid is not 0 means that this is parrent process//$PID is child process//This is the parrent Process itself, Let child become a daemon. if ($PID) die ("Daemon PID: $PID\ n ");//Starting from this, the daemon mode is executed//the current process and the terminal are detached into daemon mode if (!posix_setsid ()) Die (" Could not detach from terminal\n ") ;//Set Daemon's message function declare (ticks = 1); if (!pcntl_signal (SIGTERM, "signalfunction")) die ("Error!!! \ n "); if (!pcntl_signal (SIGTRAP, "signalfunction")) die ("Error!!! \ n "); if (!pcntl_signal (SIGCHLD, "signalfunction")) die ("Error!!! \ n ");//Establish external connection Socket $ServerSocket =socket_create (af_inet, sock_stream,sol_tcp);//Set External monitoring IP and Port,ip linked fields bit 0, Indicates that the IP if (!socket_bind ($ServerSocket, 0, $ServerPort)) die ("Cannot bind socket!\n") that listens to all interfaces, and/or starts to listen to port if (!socket_listen ($ServerSocket)) Die ("Cannot listen!\n");//sets the socket to Nonblock mode if (!socket_set_nonblock ($ServerSocket)) Die ("Cannot set Server socket to block!\n ");//emptying $pid, indicating that there is no child Process unset ($PID);  while (true) {//Enter pooling mode and check for any connections every 1 seconds.   Sleep (1);//Check to see if there is a connection at @ $C if ($ConnectedServerSocket!==false) {//a child process is connected to cola//start with a connection $PID =pcntl_fork ();   if ($PID ==-1) die ("Could not fork"); if ($PID) continue;//This is daemon process,Go back and listen.  Here is the child process start//Execute socket function processsocket ($ConnectedServerSocket);  After the socket is finished, the socket Destroysocket () is dropped;  End Child Process exit (0); } }

The above is the way to open a multi-process PHP, I hope to help you.

The above describes the PHP code sharing: Open the multi-process, including the content of the PHP code, I hope the PHP tutorial interested in a friend helpful.
