pdo drivers shows no value in linux

this is screenshot i have install php5.6 with the following command: - sudo apt-get install -y php5.6 and also install the php cli with this command : sudo apt-get install php5-cli.

then,

I have added following line to php.ini file for extenstion: extension=pdo.so and extension=pdo_mysql.so

and given the extension path : extension = /usr/lib/php/20131226/pdo_mysql.so

and use command : sudo apt-get install php-mysql

but still shows the pdo drivers no value when running phpinfo()

so, how to solve?
