Cause:
If you check the PHP's initialization file (php.ini), the problem here was the directory in which the loadable extensions (modules) reside. Usually the default directory in the php.ini is set to "/usr/lib/php/modules" but in my installation, i have "lib64" NOT "lib" and should therefore change to "/usr/lib64/php/modules"

Solution: 
You can run the command below to find location of the php modules on your installation. for example if you are looking for "json.so"
 [root@localhost]# find / -name json.so
/usr/lib64/php/modules/json.so

Problem Solved?
