将PHP5更新为PHP7 Ubuntu 14

Question

After I have updated php5 to/and installed PHP 7.

When I run php -v :

PHP 7.0.23-1+ubuntu14.04.1+deb.sury.org+1 (cli) (built: Aug 31 2017 12:52:39) ( NTS )
Copyright (c) 1997-2017 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2017 Zend Technologies
    with Zend OPcache **v7.0.23**-1+ubuntu14.04.1+deb.sury.org+1, Copyright (c) 1999-2017, by Zend Technologies

But my phpinfo() still on :

PHP Version 5.5.31-2+deb.sury.org~trusty+1

What should I do to work on PHP7 and not PHP5?

Answer 1

It is because your PHP CLI version is 7 but web is using 5.5

From php5.x to php7.0:

Web:

sudo a2dismod php5.x ; sudo a2enmod php7.0 ; sudo service apache2 restart

CLI:

sudo update-alternatives --set php /usr/bin/php7.0

From php7.0 to php5.x:

Web:

sudo a2dismod php7.0 ; sudo a2enmod php5.x ; sudo service apache2 restart

CLI:

sudo update-alternatives --set php /usr/bin/php5.x

In place of x you have to use particular version ex 5.6
