Complete!

Now you can see file bcmath.so and 20-bcmath.ini

[root@tutorialspots /]# find -name bcmath.so
./usr/lib64/php-zts/modules/bcmath.so
./usr/lib64/php/modules/bcmath.so
[root@tutorialspots /]# find -name *bcmath.ini
./etc/php.d/20-bcmath.ini
./etc/php-zts.d/20-bcmath.ini

Step 4 (optinal): create symbolic links if there aren’t these files in folder /usr/lib64/php/modules/ and /etc/php.d/

ln -s /opt/remi/php71/root/usr/lib64/php/modules/intl.so /usr/lib64/php/modules/intl.so
ln -s /etc/opt/remi/php71/php.d/20-intl.ini /etc/php.d/20-intl.ini

Step 5 (optinal): restart php-fpm if not exist bcmath module in php -m

service php-fpm restart

Done, check php -m
