PHP Hello World

Revision as of 03:18, 15 November 2005

This short article is intended for PHP programers who are interested in trying Caucho's PHP implementation.

It is written for users of windows.

Part I: Installing Resin

Downloading and unzipping Resin

1. Navigate to http://www.caucho.com/download
2. Download the latest Resin Binary for your computer. For purposes of this demo, I have downloaded the Windows .zip binary.
3. Save the file to your desktop.
4. Double click the binary and unzip the file. For purposes of this demo, I have unzipped the contents to c:\resin-3.0.14

Running Resin for the first time

1. Browse to the directory into which you unzipped the resin download (ie: c:\resin-3.0.14)
2. Double-click httpd.exe. At this point the resin web server should start.
3. Open your favorite browser and type in the following URL: http://localhost:8080
4. You will now see Resin's Default Home Page

Part II: Configuring Resin to Serve PHP Pages

1. Cut and paste the "web.xml" into your favorite text editor.
2. Save the file into c:\resin-3.0.14\webapps\ROOT\WEB-INF (NB: if you use Notepad, then be careful to either save as "all files" or just put the file name in double quotes. IE: "web.xml").
3. Cut and paste the "HelloWorld.php" into your text editor.
4. Save the file into C:\resin-3.0.14\webapps\ROOT (NB: as above, if you use Notepad, then be careful to either save as "all files" or just put the file name in double quotes. IE: "HelloWorld.php").

web.xml

<web-app xmlns="http://caucho.com/ns/resin">
  <servlet-mapping url-pattern="*.php"
                   servlet-class="com.caucho.php.servlet.PhpServlet">
    <init compile="false"/>
  </servlet-mapping>
</web-app>

HelloWorld.php

<?php
  echo "Hello World";
?>
