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(); ?>
