Edit report at https://bugs.php.net/bug.php?id=80486&edit=1 ID: 80486 Comment by: danack@php.net Reported by: php4fan at gmail dot com Summary: Undocumented backward incompatible change between 7.4.8 and 7.4.9 Status: Open Type: Documentation Problem Package: Documentation problem Operating System: all PHP Version: Irrelevant Block user comment: N Private report: N New Comment: Hey Teo, The migration guide is for migrating between versions that are meant to have changes. There is also list of bug fixes for each version: https://www.php.net/ChangeLog-7.php#PHP_7_4 but I can't currently see it listed....which is not good. There should be an entry for it as it is definitely different behaviour, so thanks for reporting it. Previous Comments: ------------------------------------------------------------------------ [2020-12-04 19:17:06] php4fan at gmail dot com Description: ------------ --- From manual page: https://php.net/migration74.incompatible --- Something has changed between 7.4.8 and 7.4.9 that affects passing parameters to a function by eference. Leaving aside the fact that such bc-breaking changes shouldn't be introduced between sub-minor versions (i.e. from x.x.y to x.x.z) to begin with, this change is not documented. I would expect to find it here: https://www.php.net/manual/en/migration74.incompatible.php (given that there is not a section named "migrating from 7.4.8 to 7.4.9) The script below runs without errors or warnings in all versions <= 7.4.8 (including ancient ones), and causes fatal errors starting from 7.4.9 See https://3v4l.org/SMK9U Test script: --------------- <?php function test(&$value) { echo $value; } test(intval(3)); Expected result: ---------------- bc-breaking change should be documented ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=80486&edit=1
