[SOLVED] how to add bcmath extension in php 5.6 with php-fpm on Centos 7

how to add bcmath extension in php 5.6 with php-fpm on Centos 7

I am trying to add bcmath extension on my Centos 7 which has PHP 5.6 installed along with nginx and php-fpm

I ran

yum install php56-bcmath

Above installed the bcmath extension which I can see under the 'module' column in phpinfo() output.

However when I call php function get_loaded_extensions, I don't see the bcmath in the loaded extension list.

I restarted php-fpm and nginx after installing bcmath package.

Am I missing anything?

output of get_loaded_extensions()

Solution

I found what was the probem.

I had multiple installations of PHP

There was a php56 version installed too which was being used by the php-fpm. So I installed bcmath library using the command below and it then got applied to the correct PHP installation.

yum install php56-php-bcmath

restarted php-fpm and there was the problem solved.
