I'm trying for about 4 hours to install PHP 7.4 on my Raspberry Pi Zero W.

I tried different tutorials, but I endup crashing my raspbian completly or just the installed php. With crashing I mean, I get the following message: Illegal instruction.

I also tried to install diffrent raspbians, but nothing worked till now.

Is it even possible to use PHP 7.4 on a raspberry pi?

1 Answer 1


First method:

You can install it manually by:

wget http://ftp.us.debian.org/debian/pool/main/p/php7.4/php7.4_7.4.1-1_all.deb 

And then:

dpkg -i php7.4_7.4.1-1_all.deb

It gives you a lot of dependencies which you must install before this package. It's the hardest method. Look at the second method which is much easier.

Second method:

Ensure your system is updated:

sudo apt update

Download and store the PPA repository in a file but first, download the GPG key:

sudo apt -y install lsb-release apt-transport-https ca-certificates

sudo wget -O /etc/apt/trusted.gpg.d/php.gpg https://packages.sury.org/php/apt.gpg

Then add the repository:

echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/php.list

The last step is to install PHP 7.4 on your Raspbian Buster. Before installation, update the system package list on added repositories:

sudo apt update

Then install PHP 7.4:

sudo apt -y install php7.4  

I just tested it and worked. I got the exact version by php -v:

PHP 7.4.2 (cli) (built: Feb  2 2020 07:53:49) ( NTS )
Copyright (c) The PHP Group
Zend Engine v3.4.0, Copyright (c) Zend Technologies
    with Zend OPcache v7.4.2, Copyright (c), by Zend Technologies

  • @clockw0rk Which method you've followed? Commented Dec 28, 2020 at 7:29

    The second one. Seems like there has changed a lot with php, wordpress and so on this year. switched to a different bloggin software now, since i could not even get nginx to install properly on raspian. they really should update the arm-package list

  • You get my upvote. Followed method 2 in feb 2021 and got the expected results on raspberry os buster. It is always nice to see a good answer which explains each step. Commented Feb 19, 2021 at 17:17
