Messaging operations

All messaging operations are performed through calls to methods on the connection object. To add a message to a queue the "send" method is used, to obtain a message from a queue the "receive" method is used. Other methods provide publish and subscribe functionality and control of transaction boundaries.

Example #1 Adding a message to a queue and receiving a response

<?php
$msg = new SAMMessage('This is a simple text message');
$msg->header->SAM_REPLY_TO = 'queue://receive/test';
$correlid = $conn->send('queue://send/test', $msg);

if (!$correlid) {
  // The Send failed!
  echo "Send failed ($conn->errno) $conn->error";
} else {
  $resp = $conn->receive('queue://receive/test', array(SAM_CORRELID => $correlid));
}
?>

Hello

I think that most people people coming here are looking to do this on client side, in client/server web applications

Sam is not made for this, but to connect servers together - systems in fact. See http://project-sam.awardspace.com/overview.htm

Since PHP is stateless it is really hard to do collaborative applications with a PHP back-end and very few solutions exist. So, for those looking for this, I put here a link to a messaging server in PHP - free open source and community driven: http://php-polling.sourceforge.net/

Hoping this will make you save time!
