Ubuntu/How to upgrade from PHP 7.0 to PHP 7.1
From Mana zināšanu grāmata
Install PHP 7.1
Lets stop our server first, then install PHP 7.1.
$ service apache2 stop
$ sudo apt-get install php7 php7.1
$ sudo apt-get install php7 php7.1
We'll also install some extra packages for our PHP installation - these are needed for Laravel and Composer!
$ sudo apt-get install php7.1-curl php7.1-xml php7.1-zip php7.1-gd php7.1-mysql php7.1-mbstring
Once that is done, lets check PHP is updated on the CLI
$ php -v
If the first row looks like this, we've done good so far! PHP 7.1.11-1+ubuntu16.04.1+deb.sury.org+1 (cli) (built: Oct 27 2017 13:49:56) ( NTS )
Remove PHP 7.0
Now we have PHP7.1, lets get rid of PHP7.0
$ sudo apt-get purge php7.0 php7.0-common
Make PHP7.1 used by Apache
Finally, we need to tell Apache to use PHP7.1 now PHP 7.0 is not being used. Lets enable the PHP mod!
$ a2enmod php7.1
$ service apache2 restart
$ service apache2 restart
