I have recently updated by php. My php -v command show following result:
PHP 7.0.6-6+donate.sury.org~precise+1 (cli) ( NTS )
Copyright (c) 1997-2016 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies
with Zend OPcache v7.0.6-dev, Copyright (c) 1999-2016, by Zend Technologies
But still phpinfo() function shows php 5.3.10 version
What should I do to start using it.
