Doc #75682 [Opn->Ver]: Undocumented PHP 7.2 BC break

Edit report at https://bugs.php.net/bug.php?id=75682&edit=1 ID: 75682 Updated by: cmb@php.net Reported by: glenn at codeacious dot com Summary: Undocumented PHP 7.2 BC break -Status: Open +Status: Verified Type: Documentation Problem Package: Documentation problem PHP Version: 7.2.0 Block user comment: N Private report: N New Comment: This behavioral change has been introduced in commit b67eb34[1] as fix for bug #73987. The bugfix targeted PHP 7.1.2 and 7.2.0, but has been reverted in the PHP-7.1 branch[2] before PHP 7.1.2 has been released. I suppose this has been done for BC reasons, and as such it would need an entry in UPGRADING and consequently in the migration guide.

This is causing errors like this when they didn't occur under 7.1: PHP Fatal error: Declaration of SubClass::foo() must be compatible with SuperClass::foo() Examples are being discussed here: https://www.drupal.org/project/drupal/issues/2923015 https://github.com/zendframework/zend-mvc/issues/266 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=75682&edit=1
