php iconv and mbstring

[bbozhkov]

Hi,
DirectAdmin v.1.658 with Jail
As non root user I can not view php iconv and mbstring.
How to enable them?
As root there are accessible
For a no root user
php -m returns:
[PHP Modules]
Core
date
filter
hash
json
libxml
openssl
pcntl
pcre
random
Reflection
session
sodium
SPL
standard
zlib

For root there are much more modules.
