Updating Adminer in Laragon for PHP 8

In Laragon, when you switching to PHP 8 and accessing adminer at http://localhost/adminer, you will find this error:

adminer error in php 8 laragon

the errors are because of the existing adminer app only supported in PHP 7. If you're currently using PHP 8 for now and the future, We need to update the adminer.

Downloading the latest Adminer app

Go to, and find the download link for the latest adminer app. Adminer is a single-file php application, so you will find a single php file like adminer-4.8.1.php downloaded for example.

Updating the existing Adminer to the latest

Go to C:\laragon\etc\apps\adminer (or adjust to your laragon directory path) and you will find a single php file index.php. You may want to delete or backup this file and replace it with adminer-4.8.1.php and rename it into index.php

Accessing the new Adminer

With PHP 8 running, now the new adminer app will be accessible in the same url and you can start to login into a database.

adminer 4.8.1 login page

as per adminer 4.6.3 or newer, you cannot login into a database with a blank password (ref), unlike the phpMyAdmin. So to use adminer, maybe you need to create a new database admin user with a password through mysql cli or phpmyadmin.

Good thing when you switch back to PHP 7.4, the latest adminer 4.8.1 still supported.

How to write a kickass README

Arguably the single most important piece of documentation for any open source project is the README. A good README not only informs people what the project does and who it is for but also how they use and contribute to it.

If you write a README without sufficient explanation of what your project does or how people can use it then it pretty much defeats the purpose of being open source as other developers are less likely to engage with or contribute towards it.
