New examples in Habari ActiveMQ Client release 2.4 show how Delphi (and Free Pascal) applications can use Apache ActiveMQ to exchange messages with PHP web applications.
First example: publish a message for every HTTP GET request
Using the open source PHP Stomp client from FuseSource, sending messages requires only a couple lines of code.
This example writes a text message to the queue TOOL.DEFAULT:
<?php
// include Stomp library
require_once("Stomp.php");
// make a connection
$con = new Stomp("tcp://127.0.0.1:61613");
// connect
$con->connect();
// send a message to the queue
$con->send("/queue/TOOL.DEFAULT", "test");
echo "Sent message with body 'test'\n";
// disconnect
$con->disconnect();
>
The demo application ConsumerTool.exe then can be used to consumer the message:
Second example: publish a message using form data of a HTTP POST request
A web form can be used to enter a custom message text. The form then sends the text to the submit.php script as a HTTP POST request.
<form method="post" action="submit.php">
Message: <br>
<textarea name="msg" cols="40" rows="5">
Enter some text here for the message body...
</textarea><br>
<input type="submit" name="Button" >
</form>
The PHP code in submit.php:
<?php
// include Stomp library
require_once("Stomp.php");
// make a connection
$con = new Stomp("tcp://127.0.0.1:61613");
// connect
$con->connect();
// send a message to the queue
$con->send("/queue/TOOL.DEFAULT", $_POST[msg]);
echo "Sent message with body: '$_POST[msg]'\n";
// disconnect
$con->disconnect();
?>
