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?

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:

    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 – clockw0rk Dec 29 '20 at 02:00
  • 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. – Thomas Carlisle Feb 19 '21 at 17:17
  • Second method is perfect as of 13 April 2021, Linux raspberrypi 4.19.66-v7.

  • At a glance, that second method is going to require specific things of the shell you're using. If you're not familiar with how to translate it, bash works for certain. Edit: I take that back, it looks like the variable expansion works in most/all shells. – Steven Fisher May 21 '21 at 19:47
