Upgrade to the specific php 7.1/7.2 from php 7.0 in Ubuntu 16.04

Question

How can I upgrade to php 7.1 from php 7.0 in ubuntu 16.04 ?

If I do a php -v I get this message:

PHP 7.0.8-0ubuntu0.16.04.3 (cli) ( NTS )
Copyright (c) 1997-2016 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies
    with Zend OPcache v7.0.8-0ubuntu0.16.04.3, Copyright (c) 1999-2016, by Zend Technologies

Why do you guys reckon Ubuntu isn't upgrading PHP to never minor versions? 7.0.8 has been superseded a few months ago. — The Onin, Dec 15 '16 at 02:10
Because even minor PHP versions break compatibility. @see hash_function in php 7.1 vs php 7 — Olavi Sau, Nov 27 '17 at 11:30

There is no official PHP 7.1 in the Ubuntu 16.04 repos.

If you want PHP 7.1, there is a version available in ppa:ondrej/php

You can install it like this:

sudo add-apt-repository ppa:ondrej/php
sudo apt-get update
(optional) sudo apt-get remove php7.0
sudo apt-get install php7.1 (from comments)

Remember that this is not an official upgrade path. The PPA is well known, and is relatively safe to use.

The PPA has co-installable packages (you can have multiple versions of PHP installed from that PPA). ~muru

Thank yoy @ThatGuy, you are right, but I need conditional return types "?" and can't wait to use them :) – Michele Carino Dec 04 '16 at 08:40
No problems. This should get you up and running :) – AnotherKiwiGuy Dec 04 '16 at 08:41

I needed to launch also: 4. sudo apt-get install php7.1 – Michele Carino Dec 04 '16 at 08:42
Nice, updated the answer to add your step :) – AnotherKiwiGuy Dec 04 '16 at 08:44
May need to do it like this:
sudo apt-get remove php7.0 and then sudo apt-get install php7.1.

May have to test that further I think :)

Thanks @muru That's actually really helpful! I've only ever installed one at a time. I think it may be my OCD kicking in ;) Added your note to the answer! – AnotherKiwiGuy Dec 04 '16 at 08:47

@ThatGuy you can write your comment as answer, just adding the php7.0 removal (if needed) and that after that any extension should be reinstalled for php 7.1 – Michele Carino Dec 04 '16 at 09:59
@Pherserk - There you go, added as an optional step :) – AnotherKiwiGuy Dec 04 '16 at 20:47

Worked for me as well on Ubuntu 16.04.01 LTS hosted on EC2. – The Onin Dec 16 '16 at 15:08
Why do 3. upgrade? If that ppa has a newer version for 7.0 it will be upgraded but what is the point when removing it seconds later? System upgrades are a nice thing to do but has are out of place when this is just about upgrading php – redanimalwar Mar 09 '17 at 21:12
@redanimalwar - The PPA does not overwrite the stock PHP. Or at least didn't at the time of writing this answer. – AnotherKiwiGuy Mar 09 '17 at 22:44
OK that makes my point even more valid. – redanimalwar Mar 10 '17 at 14:59
@redanimalwar - I'm definitely not opposed to keeping this answer up to date.
Thanks for the edit :)

So installing 7.1 from this ppa won't provide any automatic upgrade path? I'd need to install higher versions manually? – mos fetish Apr 13 '17 at 01:47
Two questions. 1. Yes it will upgrade normally as long as you continue to use the PAPA. 2. You should be testing and installing the versions manually anyway, as part of a production server, but if you run apt-get upgrade, it will upgrade as a part of the routine. – AnotherKiwiGuy Apr 15 '17 at 05:58

If you got your PHP 7.0 from this PPA in the first place then to remove it, you need to run sudo apt-get remove php7.0*, not just sudo apt-get remove php7.0 as in point 3 above. – Luke Cousins Aug 18 '17 at 13:25
@LukeCousins - Yes, but that is not the correct answer based on the OP's question. – AnotherKiwiGuy Aug 18 '17 at 14:21

This didn't work for me, i get E: Unable to locate package php7.1 E: Couldn't find any package by glob 'php7.1' E: Couldn't find any package by regex 'php7.1' – Victor Anuebunwa Oct 01 '17 at 04:23
@avonnadozie repeat step 1 and 2. It looks like the PPA has not been installed, or refreshed. – AnotherKiwiGuy Oct 01 '17 at 06:48

Unable to locate package php7.1 – Damjan Pavlica Dec 26 '17 at 23:01
@DamjanPavlica - Then it sounds like the PPA didn't get added to the apt sources. You may have to run sudo add-apt-repository ppa:ondrej/php and sudo apt-get update again. – AnotherKiwiGuy Dec 29 '17 at 07:56
@ThatGuy nope :( – Damjan Pavlica Dec 29 '17 at 15:53
@DamjanPavlica - Ok, it's out of scope for this question. It's probably best to ask a new question and refer back to this one. – AnotherKiwiGuy Dec 30 '17 at 03:14

Just to note: this repo updates also to php 7.2 – josircg Oct 28 '19 at 15:03
