Laravel Version, PHP Version and Composer Version Compatibility Issue – PHP Versions

I have installed PHP version 7.3.33, composer 1.1 and running multiple laravel 7.x projects.

Now I am trying to install two different Laravel Projects. One with Laravel 9 and the other with 7.x.

    You need to create a new environment for the laravel 9 since it’s not compatible with php 7. You can do it with docker Laravel sail or Virtual Machine Laravel homestead.

    If you’r on a production environment, i recommend you to use another server instance or deploy in a container.
    In other way, you also can use PHP-FPM with Apache / Nginx.

    If you’re on Local environment and don’t have any knowledge of admin system / devops, you can use Laragon or Wamp and install different version of PHP

    I’m on windows and how I combat this is by downloading the versions of PHP I desire and putting them inside folders that are within the same directory.
    Inside parent folder I have php72 php74 php8.

    Then I edit my path location in my terminal and point to that same folder however I reference the folder php.

    Assuming in my directory I have php72 php74 php8 and I wish to use php8 I would rename that folder to just php

    Now my directory looks like this php72 php74 php

    If I need to change to php72 I would rename the directories as below
    php php74 php8

    I also implement a similar solution for composer

    It’s a bit of weird hacky way, however its easy to implement and works for me, hopefully it can for you too.

    It’s because in your project in composer.json file you have:

    "require": {
    "php": "^7.4",
    .....
},

    Try to update this requirement to:

    "require": {
    "php": "^7.4|^8.0",
    .....
},

    Or another option if you wouldn’t to install any new version PHP you can do this. It will ignore reqs.

     composer install --ignore-platform-reqs

    I also had the same problem. I solved it with this:

    composer require laravel/sail:*
