PHP hello world

This code sample is a "hello world" application that runs on PHP. The sample illustrates how to complete the following tasks:

  • Set up authentication
  • Connect to a Bigtable instance.
  • Create a new table.
  • Write data to the table.
  • Read the data back.
  • Delete the table.

Set up authentication

To use the Python samples on this page in a local development environment, install and initialize the gcloud CLI, and then set up Application Default Credentials with your user credentials.

  1. Install the Google Cloud CLI.

  2. If you're using an external identity provider (IdP), you must first sign in to the gcloud CLI with your federated identity.

  3. If you're using a local shell, then create local authentication credentials for your user account: 

    gcloud auth application-default login
