如何从5.6更新Google Compute Engine中的PHP？

Question

THere's a complete lack of information about Google Compute Engine and upgrading PHP Versions (it all seems to refer to App Engine).

Anyway, I'm running a Wordpress install on php 5.6, and need to upgrade to 7.3.

I can confirm this in the console by php -v returning 5.6.17-0+deb8u1 (cli) (build: Jan 13 2016 09:10:12)

Are there any decent instructions or guidelines on how to properly update this to the latest version of PHP?

Answer 1

GCE offers you a virtual machine, so, in the end, to update your version to the latest of right now (7.3), you have to do as you would do with a normal system.

Since you are using Debian, you can find how to update to the latest PHP version here .

1. Update your system with sudo apt upgrade -y
2. Add the repository:

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

echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/php7.3.list

3. Update and install PHP: sudo apt update && sudo apt -y install php7.3
