Bug #77025 [NEW]: mb_strpos throws Unknown encoding or conversion error
From: vs-php-bugs at schukai dot com
Operating system: debian/stretch
PHP version: 7.3.0RC3
Package: mbstring related
Bug Type: Bug
Bug description:mb_strpos throws Unknown encoding or conversion error
Description:
------------
the following code works as expected
php7.2 -r "echo \mb_stripos('Hello', 'e', 0, '8bit');"
> 1
in 7.3, however, a error is thrown
php7.3 -r "echo \mb_strpos('Hello', 'e', 0, '8bit');"
> php error
alternatively, mb_stripos does not write any output
php7.3 -r "echo \mb_stripos('Hello', 'e', 0, '8bit');"
> empty result
the following code works with iso-8859-1
php7.3 -r "echo \mb_stripos('Hello', 'e', 0, 'iso-8859-1');"
php7.3 -r "print_r(mb_list_encodings());" contains 8bit and iso-8859-1
Array
(
[0] => pass
[1] => auto
[2] => wchar
[3] => byte2be
[4] => byte2le
[5] => byte4be
[6] => byte4le
[7] => BASE64
[8] => UUENCODE
[9] => HTML-ENTITIES
[10] => Quoted-Printable
[11] => 7bit
[12] => 8bit
[13] => UCS-4
[14] => UCS-4BE
7.2/php.ini and 7.3/php.ini are identical
