Hi,
in our doc for 4.0.x, the PHP requirements mention these (among other lines):
----------- You need PHP 5.2.0 or newer, with ``session`` support, the Standard PHP Library (SPL) extension and JSON support.
For proper support of multibyte strings (eg. UTF-8, which is currently the default), you should install the ``mbstring`` and ``ctype`` extensions. -----------
It would be simpler to say:
----------- You need PHP 5.2.0 or newer, with ``session`` support, the Standard PHP Library (SPL) extension, JSON support, and the ``mbstring`` and ``ctype`` extensions. -----------
I would use this as a doc fix for https://sourceforge.net/p/phpmyadmin/bugs/4036/
