PHP

New PHP versions are released every year and come with important improvements and changes compared with previous versions. Moodle tries to support them as soon as possible, always matching them with our own scheduled release plans.

Policy statement

Since 3.5

We always follow this agreed policy regarding PHP and Moodle supported versions:

  1. A LTS will always require the previous LTS (or later) for upgrading.
  2. The maximum PHP version supported for a branch will be the max one achieved along the life of the branch. Usually with .0 releases but may happen later (we added support for php74 with 3.8.3, or support for php80 with 3.11.8, for example).
  3. The minimum PHP version supported for a branch will be the lower of:
    • The minimum version supported in any way by php the day of the Moodle release (so we provide slow, progressive increments).
    • The maximum PHP version supported by the previous LTS branch (so we guarantee jumping between LTS is possible without upgrading PHP at the same time).

Since Moodle 3.5 (MDL-59159), these rules apply to decide Minimum PHP and Moodle versions supported:
# A LTS will always require the previous LTS (or later) for upgrading.
# The maximum PHP version supported for a branch will be the max one achieved along the life of the branch. Usually with .0 releases but may happen later (we added support for php70 with 3.0.1, or support for php73 with 3.6.4, for example).
# The minimum PHP version supported for a branch will be *the lower of*:
-- The [minimum version supported in any way by php|http://php.net/supported-versions.php] the day of the Moodle release (so we provide slow, progressive increments).
-- The maximum PHP version supported by the previous LTS branch (so we guarantee jumping between LTS is possible without upgrading PHP at the same time).{panel}
