== '''Install PHP 7.1''' ==

Lets stop our server first, then install PHP 7.1.
<div style="background:#eee;  border:1px solid #ccc;  padding:5px 10px">$ service apache2 stop<br/> $ sudo apt-get install php7 php7.1</div> 
We'll also install some extra packages for our PHP installation - these are needed for Laravel and Composer!
<div style="background:#eee;  border:1px solid #ccc;  padding:5px 10px">$ sudo apt-get install php7.1-curl php7.1-xml php7.1-zip php7.1-gd php7.1-mysql php7.1-mbstring</div> 
Once that is done, lets check PHP is updated on the CLI
<div style="background:#eee;  border:1px solid #ccc;  padding:5px 10px">$ php -v</div> 
If the first row looks like this, we've done good so far!<span>&nbsp;</span>'''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
<div style="background:#eee;  border:1px solid #ccc;  padding:5px 10px">$ sudo apt-get purge php7.0 php7.0-common</div> 
== '''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!
<div style="background:#eee;  border:1px solid #ccc;  padding:5px 10px">$ a2enmod php7.1<br/> $ service apache2 restart</div>
