CiviCRM support for PHP 8.1?

Question

Drupal 9 has now deprecated PHP 7.4. CiviCRM gives lots of deprecated and warning messages under PHP 8.1. It is possible to suppress them by adding

// PHP 8.1 generates lots of warnings that 7.4 does not.
error_reporting(E_ALL & ~E_DEPRECATED & ~E_WARNING);

immediately before

require_once 'CRM/Core/ClassLoader.php';
CRM_Core_ClassLoader::singleton()->register();

at the bottom of civicrm.settings.php. However, are there plans to change the code so those warnings are no longer given? It is surely better to make sure the code doesn't give deprecated and warning messages?

Answer 1

Yes it's just a large task and they're getting fixed but slowly. Unlike every other language on the planet php itself has greatly changed, and keeps changing every couple months. As a comparison, imagine if javascript now decided to output warnings when doing something like a + b and a=2 and b=null. So much javascript on the internet would be throwing warnings and need changing.
