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.
