After doing a lot of experiments I finally fixed the issue. The solution is as below:

cd /etc/php.d/

And create a file named solr.ini.

Added this line:

extension=solr.so

And now I have to remove the above extension from the php.ini file and restart php-fpm

That's all, worked for me.

Still got error. Realized you need to load solr.so after json.so, so the json symbols are in memory before solr is loaded, otherwise solr fails to load.

On centos and Red Hat Enterprise Server simply give solr the highest number out of the numbered ini files in /etc/php.d. You may just need to make it load after json.ini, but I'm loading it last and now it works. I named it 60-solr.ini and it started working.
