'PHP Deprecated issue when running artisan command

Whenever I run an artisan command I am getting this issue.

I am using Valet and PHP 8.1. I have tried changing versions of PHP but I still get this issue.

When i run:

jakefeeley@Jakes-MBP marketing % php artisan plugin:install vojtasvoboda.twigextensions

Returns:

In my experience this is due to attempting to run Laravel 7 (or earlier) under PHP 8.1. I know you said you tried changing PHP versions, but I would double-check that your changes definitely took effect.

For Laravel 7, switching back to PHP 8.0 fixed the issue for me.

nb: Laravel 7's composer.json incorrectly specifies "php": "^7.2.5|^8.0", which implies it can run under PHP 8.1.

Solution 2:[2]

I had the same problem when i update my php version from 7 to 8. I updated "laravel/framework" to "^8.75" and ran composer update. That works for me.

Solution 3:[3]

I ran composer update and it fixed things

Solution 4:[4]

In my case, i had Laravel 8.12 then i got this error. so i change "laravel/framework": "^8.12", to "laravel/framework": "^8.75", in Composer.json . then i ran composer update on terminal. there you go!

*at the end, when i ran php artisan --version my laravel version was 8.83.1

Solution 5:[5]

I was having same issues due to the laravel/php versions, I was using laravel 6.X LTS and php 8.1 which is not compatible as you can check here https://laravel.com/docs/9.x/releases so you have two choices either upgrade your laravel or downgrade your php, im my case I was using Homestead & Vagrant so in your sites entry of your Homestead.yaml you can do something like

sites:
    - map: your-site.local
      to: /home/vagrant/your-site/public
      php: "7.4"

Or any php version you want to use and run vagrant reload --provision

Solution 6:[6]

I got the same error when I tried to run Laravel 7.3 on php 8.1

For me i had 2 versions of php installed php-7.4 and php-8.1.

When i checked on command line interface the version of php, using the command php --version i got php 7.4

So I thought php 7.4 was what laravel was using, But that was not the case. The web server (nginx) was redirecting to php 8.1

Tip for debuging:

copy index.php for backup (store it aside)

then remove everything on index.php add the following

<?php
   phpinfo();
?>

Try to access it. That will give you php information page that will contain the version of php your laravel installation is using.

As i was using brew on macos Big sur, i used these commands to stop php8.1

brew services stop [email protected]  

Starting php 7.4

brew services start [email protected]

For more info on switching php versions
