Laravel Version, PHP Version and Composer Version Compatibility Issue

Question

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.

this seems like an environment issue. One laravel version runs on PHP 7, while the other requires PHP 8+. So if you want to keep both of those running you have to find a way to run both php versions (or update the oldest project to the newest laravel version) — Flame

I am working on Local. I already tried with Laragon. But composer error still remains. If I update the composer, all existing projects will stop working. How can fix composer issue? Currently I am using XAMPP. Can I use both XAMPP and Laragon at the same time.? — hasnain

"If I update the composer, all existing projects will stop working". What does this mean? Are you updating the version of Composer or are you running composer update inside your project to update the composer.json versions? For the last case, you should never be able to screw up other projects since you are working in a project context. — Flame

you can try to install latest XAMPP on different drive and can use that for the latest version. — Sonu Sindhu

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.

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

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:*

This needs to change your PHP version use the next:

sudo update-alternatives --config php

Type selection number: 5 to chose the version php8.0
