How to Upgrade PHP to Latest Version

PHP7.4 has been released with a handful of new features — like the arrow function array_map(fn (Foo $foo) => $foo->id, $foo), typed properties and array spread operator ['foo', ...$foo, ...$bar]; — and that it’s also faster compared to PHP7.3.

So if you’re thinking to update PHP on your machine, take a look at the following post in which I’ll show you how to do so in several ways.

Shortcuts to:

Upgrading PHP in macOS

To begin with, you’ll have to check the PHP version that’s currently installed in your system by typing the following command line:

php -v

As we can see below, we are currently using PHP 7.3.7 on our macOS.

php version macos

Arguably the easiest way to install and update PHP on your macOS machine is by using Homebrew. Homebrew is a package manager for macOS though it is now also available in Linux and Windows too. With Homebrew, you can type the following command.

brew upgrade php

The process may take a bit long, however, once it’s done you can run the php -v command again. You should now see that the version is updated:

php74

Upgrading PHP in Windows

If you’re using Windows, it’s much easier to run your PHP application on a pre-packaged localhost environments such as WAMP or MAMP. These applications comes with PHP pre-installed and configured. You will just need to update them to their latest version or install it using the built-in tool to get the latest PHP version.

In addition to that, both WAMP and MAMP provide an option within the application to switch PHP easily.

Upgrading PHP in Ubuntu

As mentioned previously, you should first check the PHP version that’s in your Ubuntu machine.

php and ubuntu

As you can see above, currently I have PHP7.3 installed. In Ubuntu, the PHP package can be installed from the ondrej/php respository. First, run the following command to tap the repository.

sudo add-apt-repository ppa:ondrej/php
sudo apt-get update

Then, we can run the following commands which will install PHP7.4, some PHP extensions and packages, and the PHP CLI.

sudo apt-get install php7.4 php7.4-common php7.4-cli

That’s all. Your Ubuntu machine will successfully be running PHP7.4 and you can confirm by running the php -v command again.

Upgrading PHP in Docker

The latest PHP version is also available as an official Docker image. Docker is compatible in several different platforms including macOS, Windows, and Linux so you should be able to follow the same procedure for all these operating systems.

To do so, first I’d like to see if I have the Docker image for PHP7.4 in my machine.

php docker images

It looks like that I don’t have it yet. Let’s type the following command to download the image. This command will download the Docker image for PHP7.4 in the Alpine Linux flavour which smaller than the Debian-based image thus also faster to download. You can find the full list of the Docker image available in Docker Hub.

docker pull php:7.4-fpm-alpine

Once downloaded, we could run it as standalone container with this command below:

docker run --rm -i -t php:7.4-fpm-alpine sh

The container should be up and running in a second and immediately creates a Shell session inside the container. If we run the php -v, we should be seeing that it is the PHP7.4 within the Docker container.

php docker run

Wrapping Up

That’s all how to install and update PHP version to the latest. It’s not as complicated as you’d expected, isn’t it? Finally, PHP core development is progressing at a rapidly with PHP8 aimed for the next release by the end of this year with, of course, some interesting features and improvements. It’s an exciting time to be a PHP developer.
