Example Synology package written in PHP to show the 'Hello World' message.
This is the example code for my blog post at http://www.robvanaarle.nl/blog/2014/08/embedded-php-app-without-dependencies-for-synology-nas/
Run build.sh to create the package (HelloWorldPhp.spk) and manually install it on your Synology NAS. Select the HelloWorld app from the main menu to run it.
