This app demonstrates how to set up Stackdriver Trace on App Engine Standard for PHP 7.2.

• Install composer

• Install dependencies by running:

  composer install

• Install the Google Cloud SDK.

You can run these samples locally using PHP's build-in web server:

# export environemnt variables locally which are set by app engine when deployed
export GOOGLE_CLOUD_PROJECT=YOUR_PROJECT_ID

# Run PHP's built-in web server
php -S localhost:8000

You will then be able to see your application traces in the Trace UI.

Deploy the samples by doing the following:

gcloud config set project YOUR_PROJECT_ID
gcloud app deploy
gcloud app browse

The last command will open https://{YOUR_PROJECT_ID}.appspot.com/ in your browser. Browse to / to execute a trace. You will then be able to see your traces in the Trace UI.
