Hello World PHP

This version of the app uses a buildpack that is suitable for the HP Helion Development Platform v1.3. Please check the 1.0 branch if you are using v1.0.

New users should check out the resources available at HP Helion Docs. The site includes more detail and has instructions on how to create an HP Helion Development Platform Application Lifecycle Services Cluster.

To create an app in PHP, the only mandatory files are the index.php and manifest.yml files if you are using the Cloud Foundry PHP buildpack.

Manifest.yml is a config file used to specify settings that would otherwise be specified by the Helion CLI. For PHP, only the name and buildpack fields are required. The buildpack field is a URL for the buildpack that supports the necessary language and/or framework. A blank composer.json file may be necessary for certain PHP buildpacks but is not required for this particular buildpack. If you decide to use another PHP buildpack, please refer to the buildpack's documentation as well.

To ensure that your PHP applications continue to perform as expected, it is advisable to use a stable branch or tagged release of a buildpack. For example, the manifest.yml could specify a specific tagged release with the following:

buildpack: https://github.com/cloudfoundry/php-buildpack#v3.1.0

This app uses the Cloud Foundry PHP buildpack

Prerequisites

• If you do not have an HP Helion Development Platform Application Lifecycle Services Cluster available, please create one before continuing. You will also need to install the Helion CLI, which can be installed from the cluster's Management Console. Please refer to HP Helion Docs for further details.
• Composer is not necessary for this sample. While there is an empty composer.json file in this sample app, it's included to get rid of any potential warnings due to a missing composer.json file.

Deploy the Application

To deploy the application, make sure you have the Helion CLI/client installed. Execute the following commands:

• Open the terminal

• If you are not already there, cd to the root directory of the sample. The root directory contains the manifest.yml file which helps automate deployment.

• If you have not logged in to your target environment yet, execute the following:

  helion target https://api.example.com

  helion login

  Enter your Management Console credentials

  helion push

  Hit enter to accept any default values that you may be prompted for. Note: By default, ALS clusters are configured with two domains (private and public). In some situations, the Helion CLI may prompt you to select a target domain. If prompted, select the public domain from the given list (e.g. https://api.example.com)

View and run the app

• Go to the management console (e.g. https://api.example.com)
• Check the applications link to see a list of your apps.
• Click on the name of the app you just deployed. The app name is specified in manifest.yml.
• Click "View App" to see your app in action.

The result when visiting the application page and clicking 'View App' should be a page with the text "Hello World".
