MBSTRING PHP 7 conflicts with PHP5

Having problem installing mbstring on your Centos 7 Server running php 5.5.x and php 7.x  In my case php-mbstring for php 7.x is missing!

Solutions:

yum install scl-utils

yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm

yum install php70-php-mbstring

With this you have PHP7 and php-mbstring extension running next to the other PHP versions!

Don’t forget to restart your apache webserver

systemctl restart httpd

Enjoy!
