php

The php commands control the PHP engine of one environment.

kinstactl php restart my-site --env live
kinstactl php version my-site --env live
kinstactl php version my-site 8.3 --env staging

Both commands act on one environment, so pass --env in scripts; see Sites and environments. Changes wait for Kinsta to finish by default, and accept --no-wait, --timeout <minutes> and --dry-run; see operations.

php restart

Restart the PHP engine of an environment.

kinstactl php restart my-site --env live

kinstactl php restart [site] [options]

Restart the PHP engine of an environment

Arguments

Argument	Description
site	site name, display name or ID

Options

Option	Description
--env <environment>	environment name or ID
--dry-run	print the resolved target and request; change nothing
--no-wait	return the operation ID instead of waiting
--timeout <minutes>	give up waiting after this many minutes (default 30)

Global options --profile, --json and --no-input apply too. See scripting and CI.

Kinsta API: POST /sites/tools/restart-php

Restarting PHP drops the running PHP processes, for example to pick up a changed setting or to recover from stuck workers. It does not ask for confirmation. To change the number of PHP threads or the memory per thread instead, see sites php-allocation.

php version

Show the PHP version of an environment, or change it.

kinstactl php version my-site 8.3 --env staging

kinstactl php version <site> [version] [options]

Show the PHP version of an environment, or change it

Arguments

Argument	Description
site	site name, display name or ID
version	PHP version to switch to, e.g. 8.3

Options

Option	Description
--env <environment>	environment name or ID
--no-auto-update	opt out of automatic PHP updates
--dry-run	print the resolved target and request; change nothing
--no-wait	return the operation ID instead of waiting
--timeout <minutes>	give up waiting after this many minutes (default 30)

Global options --profile, --json and --no-input apply too. See scripting and CI.

Kinsta API: GET /sites/{site_id}/environments, PUT /sites/tools/modify-php-version

Without a version, the command prints the current PHP version of the environment, in the same form (8.3) that you pass to change it:

kinstactl php version my-site --env live

With a version, the environment is switched to it. --no-auto-update opts the environment out of automatic PHP updates, and only makes sense together with a version: without one it fails with a USAGE error. Try a new version on a staging environment first, and use --dry-run to check the request.
