PHP 5 has reached end of support and will be deprecated on January 31, 2026. After deprecation, you won't be able to deploy PHP 5 applications, even if your organization previously used an organization policy to re-enable deployments of legacy runtimes. Your existing PHP 5 applications will continue to run and receive traffic after their deprecation date. We recommend that you migrate to the latest supported version of PHP.

This page describes some limitations with using the local development server (dev_appserver) to test push queues in your application. In most respects, you set up your queues and tasks just as you would to run them in the App Engine production environment, but there are some differences:
The development server doesn't respect the rate and bucket-size attributes of your queues. As a result, tasks are executed as close to their ETA as possible. Setting a rate of 0 doesn't prevent tasks from being executed automatically.
The development server doesn't preserve queue state across restarts.
To prevent push tasks from running in the development server at all, use the following command:
python2 DEVAPPSERVER_ROOT/google_appengine/dev_appserver.py --enable_task_running no
Replace DEVAPPSERVER_ROOT with the path to the folder where you extract the archived version of devapp_server.py. For more information about downloading and using the archived version of dev_appserver.py, see Using the local development server.
