Versions of PHP on a VIP Platform WordPress environment can be managed in the Software Management panel of the VIP Dashboard.

VIP only supports versions of PHP that are currently eligible for security fixes ( 7.4, 8.0, and 8.1).


WordPress environments on the VIP Platform that are not yet updated to PHP 8.x by the 15th of November 2022 will be automatically updated to PHP 8.0.

PHP’s Semantic Versioning structures release versions as <major>.<minor>.<patch> to indicate if a release is major, minor, or security related.

Advance notice and scheduling details for upcoming major release versions are posted in the VIP Lobby.

As a major release approaches, non-production environments should be upgraded to the new release version. This allows application code to be tested against the new release version prior to an upgrade on production, and helps to ensure that the upgrade process goes smoothly.

Default settings

By default, PHP’s memory_limit on VIP Platform WordPress environments is set to 512MB. WP_MEMORY_LIMIT is set to 40MB for WordPress single sites, and 64MB for WordPress multisites. If a site’s WP_MEMORY_LIMIT is set to a value higher than memory_limit, WordPress will allow WP_MEMORY_LIMIT to override the PHP memory_limit.
