Edit report at https://bugs.php.net/bug.php?id=73076&edit=1 ID: 73076 Updated by: cmb@php.net Reported by: lars at moelleken dot org Summary: php compatibility: mb_strpos() Status: Open -Type: Bug +Type: Documentation Problem -Package: Strings related +Package: mbstring related Operating System: Ubuntu 12.04.5 LTS PHP Version: 7.1.0RC1 Block user comment: N Private report: N New Comment: This behavioral change is caused by a deliberate improvement, namely to generalize the support for negative string offsets, see <https://wiki.php.net/rfc/negative-string-offsets>. While this change is mentioned in UPGRADING[1] it is apparently not yet documented in the manual. Therefore I'm changing to doc-bug.
