Instrument PHP apps for Error Reporting

You can send error reports to Error Reporting from PHP applications by using the Error Reporting library for PHP. Use the Error Reporting library for PHP to create error groups for the following cases:

• Your log bucket has customer-managed encryption keys (CMEK).
• Your log buckets aren't in the global region.
• You want to report custom error events.

Error Reporting is integrated with some Google Cloud services, such as App Engine, Compute Engine, and Google Kubernetes Engine. Error Reporting displays the errors that are logged to Cloud Logging by applications running on those services. For more information, go to Running on Google Cloud on this page.

You can also send error data to Error Reporting using Logging. For information on the data formatting requirements, read Formatting error messages in Logging.

Before you begin

1. Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.

2. In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

   Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.

   Go to project selector

3. Make sure that billing is enabled for your Google Cloud project.

4. Enable the Error Reporting API .

Install the client library

The Error Reporting library for PHP lets you monitor and view errors reported by PHP applications running nearly anywhere.

For more information on installation, read the documentation for the Error Reporting library for PHP. You can also report issues using the issue tracker.

Configure the client library

You can customize the behavior of the Error Reporting library for PHP. See the library's configuration for a list of possible configuration options.

Run apps on Google Cloud

To create error groups by using projects.events.report, your service account requires the Error Reporting Writer role (roles/errorreporting.writer).

Some Google Cloud services automatically grant the Error Reporting Writer role (roles/errorreporting.writer) to the appropriate service account. However, you must grant this role to the appropriate service account for some services.

App Engine flexible environment

App Engine grants the Error Reporting Writer role (roles/errorreporting.writer) to your default service account automatically.

The Error Reporting library for PHP can be used without needing to explicitly provide credentials.

To enable Error Reporting on App Engine flexible environment, follow these steps:

1. Install necessary libraries with the following command:

   $ composer require google/cloud-error-reporting

2. Add the following line to runtime_config section in app.yaml:

appengine/flexible/logging/app.yaml

View on GitHub Feedback

enable_stackdriver_integration: true

Then the library automatically collects all the errors and uncaught exceptions to Error Reporting. If you're using a Web Framework which installs its own Exception handlers, see Framework Integrations section for more information.

Google Kubernetes Engine

To use Error Reporting with Google Kubernetes Engine, do the following:

1. Ensure that the service account to be used by your container has been granted the Error Reporting Writer role (roles/errorreporting.writer).

   You can use either the Compute Engine default service account or a custom service account.

   For information about granting roles, see Manage access to projects, folders, and organizations.

2. Create your cluster and grant the cluster the cloud-platform access scope.

   For example, the following create command specifies the cloud-platform access scope and a service account:

   gcloud container clusters create CLUSTER_NAME --service-account  SERVICE_ACCT_NAME --scopes=cloud-platform
   

Note: After you create a cluster, you can't change its service account.

Compute Engine

To use Error Reporting with Compute Engine VM instances, do the following:

1. Ensure that the service account to be used by your VM instance has been granted the Error Reporting Writer role (roles/errorreporting.writer).

   You can use either the Compute Engine default service account or a custom service account.

   For information about granting roles, see Manage access to projects, folders, and organizations.

2. In the navigation panel of the Google Cloud console, select Compute Engine, and then select VM instances:

   Go to VM instances

3. Select the VM instance that you want to receive the cloud-platform access scope.

4. Click Stop, and then click Edit.

5. In the Identity and API access section, select a service account that has the Error Reporting Writer role (roles/errorreporting.writer).

6. In the Access scopes section, select Allow full access to all Cloud APIs, and then save your changes.

7. Click Start/Resume.

Example

1. Install cloud libraries with the following command:

$ composer require google/cloud-error-reporting

2. Add the following line to your php.ini, where WORKSPACE is the absolute path to your workspace's root directory:

auto_prepend_file='/WORKSPACE/vendor/google/cloud-error-reporting/src/prepend.php'

This prepend file installs an exception handler and an error handler which automatically send errors to Error Reporting.

If you're using App Engine flexible environment, see App Engine flexible environment on this page.

Run apps in a local development environment

To use the Error Reporting library for PHP in a local development environment, such as running the library on your own workstation, you must provide your Error Reporting library for PHP with the local application default credentials. For more information, see Authenticate to Error Reporting.

To use the PHP samples on this page from 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. To initialize the gcloud CLI, run the following command:

   gcloud init

3. Create local authentication credentials for your Google Account:

   gcloud auth application-default login

   Note: If the gcloud CLI prints a warning that your account doesn't have the serviceusage.services.use permission, then some gcloud CLI commands and client libraries might not work. Ask an administrator to grant you the Service Usage Consumer IAM role (roles/serviceusage.serviceUsageConsumer), then run the following command:

   gcloud auth application-default set-quota-project PROJECT_ID

For more information, see Set up authentication for a local development environment.

The projects.events.report method also supports API keys. If you want to use API keys for authentication, you do not need to set up a local Application Default Credentials file. For more information, see Create an API key in the Google Cloud authentication documentation.

Viewing error reports

In the navigation panel of the Google Cloud console, select Error Reporting, and then select your Google Cloud project:

Go to Error Reporting

For more information, see Viewing Errors.

Framework Integrations

Some web frameworks override the exception handler. Following are examples for enabling Error Reporting with Laravel and Symfony. For other frameworks, you can use Google\Cloud\ErrorReporting\Bootstrap::exceptionHandler as the exception handler.

Laravel

Edit the report function in the file app/Exceptions/Handler.php as follows:

appengine/standard/laravel-framework/app/Exceptions/Handler.php

View on GitHub Feedback

public function report(Exception $exception)
{
    if (isset($_SERVER['GAE_SERVICE'])) {
        // Ensure Stackdriver is initialized and handle the exception
        Bootstrap::init();
        Bootstrap::exceptionHandler($exception);
    } else {
        parent::report($exception);
    }
}

You also need to add a one-line use statement at the beginning of the file:

use Google\Cloud\ErrorReporting\Bootstrap;

Symfony

Create a new file src/AppBundle/EventSubscriber/ExceptionSubscriber.php with the following content:

appengine/flexible/symfony/src/AppBundle/EventSubscriber/ExceptionSubscriber.php

View on GitHub Feedback

// src/AppBundle/EventSubscriber/ExceptionSubscriber.php
namespace AppBundle\EventSubscriber;

use Google\Cloud\ErrorReporting\Bootstrap;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\HttpKernel\Event\ExceptionEvent;
use Symfony\Component\HttpKernel\KernelEvents;

class ExceptionSubscriber implements EventSubscriberInterface
{
    public static function getSubscribedEvents()
    {
        // return the subscribed events, their methods and priorities
        return [KernelEvents::EXCEPTION => [
            ['logException', 0]
        ]];
    }

    public function logException(ExceptionEvent $event)
    {
        $exception = $event->getThrowable();
        Bootstrap::exceptionHandler($exception);
    }
}
