This article describes the message communication mechanism of PHP. Share to everyone for your reference, specific as follows:

<?php error_reporting (E_all&~e_warning&~e_notice); /** * Example for sending and receiving Messages via the "System V" \ * To try this script run it synchron/ Asynchron twice times. One time with-type=send and one time with type=receive * * @author Thomas eimers-mehrkanal GmbH * * This docum

Header (' Content-type:text/plain; charset=iso-8859-1 ');
echo "start...\n"; Create System V message Queue.
Integer value is the number of the Queue//$queue = Msg_get_queue (100379);
$MESG _key = Ftok (__file__, ' m ');
$MESG _id = Msg_get_queue ($mesg _key, 0666);
$queue = $MESG _id; Sendoptions $serialize _needed=false;
Must the transfer data be serialized?    $block _send=false; Block if message could not is send (Queue full ...)    (true/false) $msgtype _send=1; Any Integer above 0. It signeds every message.
So, could handle multible message/type in one Queue.    Receiveoptions $msgtype _receive=1; Whiche type of message we want to receive? (Here, the type is the same as the type "we send,//But if you set it to 0" you receive the "Next message" in
The Queue with any type.       $maxsize = 100;
How Long's the maximal data you are like to receive. $option _receive=msg_ipc_nowait;
             If There are no messages of the wanted type in the Queue continue without.
If is set to NULL wait for a message.
  Send or receive Messages for ($i =0; $i <20; $i + +) {sleep (1);
  Ob_flush ();
 Flush ();   $message = ' Hello, this is Flandy,now '. Date (' H:i:s ', Time ()); Transfering Data//This one sends if (isset ($_get[' type ')) &&$_get[' type ']== ' send ') {if Msg_send ($queue, $ Msgtype_send, $message, $serialize _needed, $block _send, $err) ===true) {echo "the". $i. " Message has been sent, THe messge are ". $message."
  \ n ";
  else {var_dump ($err);
   }//This one received} else {$queue _status=msg_stat_queue ($queue); Echo ' Get Messages in the queue: '. $queue _status[' Msg_qnum ']. "
   \ n ";
   Print_r ($queue _status);
  echo "\ n"; if ($queue _status[' Msg_qnum ']>0) {if (Msg_receive ($queue, $msgtype _receive, $msgtype _erhalten, $maxsize, $daten, $ serialize_needed, $option _receive, $err) ===true) {echo "Received data:". $daten. "
   \ n ";
   else {var_dump ($err);
