I'm currently using following PHP version on this machine:
Command used to get the below info at terminal :
Details I got are as below :
PHP 5.5.19-1+deb.sury.org~precise+1 (cli) (built: Nov 19 2014 19:32:34) Copyright (c) 1997-2014 The PHP Group Zend Engine v2.5.0, Copyright (c) 1998-2014 Zend Technologies with Zend OPcache v7.0.4-dev, Copyright (c) 1999-2014, by Zend Technologies

sudo apt-get update
Some information appeared. Then I again hit the following command:
but still the PHP software didn't update.
How should I do this?
