Then this is unlikely to be a PHP issue. ------------------------------------------------------------------------ [2020-09-07 07:20:03] 397836525 at qq dot com Hi there, I finally find out that the reason to problem is actually the environment. I was using the docker with the WSL 2 based engine under the Windows system. As soon as I changed the docker engine into Legacy Hyper-V backend, the problem disappeared. ------------------------------------------------------------------------ [2020-09-07 07:15:59] cmb@php.net For some reason I missed that script. Anyhow, I cannot reproduce the issue with that script. All six methods return the expected 65. ------------------------------------------------------------------------ [2020-09-04 08:23:25] 397836525 at qq dot com Somehow I cannot upload my test code by using patch file.So I paste the test code in the previos comment.please check. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
