PHP 7.1 bcmath not working

Question

I am using Ubuntu 16 server to test with php7.1. One of my apps uses a feature bcadd. I know that for this I need to install the module bcmath, but I can not find php7.1-bcmath. When I tried to install apt install php-bcmath, he just installed the module php7.0-bcmath.

I could not find the module php7.1-bcmathto install on my server. Does anyone have an idea?

apt install php7.1-bcmath returned below

E: Unable to locate package php7.1-bcmath

E: Couldn't find any package by glob 'php7.1-bcmath'

E: Couldn't find any package by regex 'php7.1-bcmath'

Answer 1

Answering my question. I managed to fix this problem with the subsequent repo update.

add-apt-repository ppa:ondrej/php
apt update
apt install php7.1-bcmath

Restart apache and everything will be fine.
