Composer does not run with differend php version

Question

I have a dev-server where multiple sites are running in development. Most of them use php8.1

Now for a new project I wanted to run php8.2

According to this answer https://stackoverflow.com/a/54736948/12848667 and several blog posts I found on the internet, I set my composer to a specific php version. But it does not seem to work.

In composer.json:

"config": {
    "optimize-autoloader": true,
    "prepend-autoloader": false,
    "platform": {
        "php": "8.2"
    }
},
"scripts": {
    "php-version": "composer -vvv about"
},

But the output of "php-version" still shows 8.1

$ composer php-version
> composer -vvv about
Running 2.4.4 (2022-10-27 14:39:29) with PHP 8.1.18 on Linux / 5.10.0-22-amd64

what am I missing?

Edit: php8.2 is installed in fpm and cli version

$ which php8.2
/usr/bin/php8.2

Error? There is no error. composer is running with php8.1 not with php8.2 as stated in composer.json — user6329530, Jun 01 '23 at 09:49

`platform` does not modify which PHP version is used to run Composer — Nico Haase, Jun 01 '23 at 10:08
@NicoHaase as stated in my question, I referred to this answer — user6329530, Jun 01 '23 at 10:16
And what did you learn from it? How did you apply it to run Composer using PHP 8.2? — Nico Haase, Jun 01 '23 at 10:30

You need to switch from the default version to the desired one.

Check default version (it should return 8.1)

php -v

Disable PHP 8.1 module (check output to restart any service)

sudo a2dismod php8.1

Enable PHP 8.2

sudo a2enmod php8.2

Set PHP 8.2 as default version

sudo update-alternatives --set php /usr/bin/php8.2

For other PHP extensions, set them as default too

sudo update-alternatives --set phar /usr/bin/phar8.2

restart Apache

sudo systemctl restart apache2

Check if version is defaulted to 8.2

php -v

`composer config` won't help to run Composer with a different PHP version, nor is`a2enmod` neccessary to run PHP on the shell – Nico Haase Jun 01 '23 at 10:30
@NicoHaase spit a source too negative – jmvcollaborator Jun 01 '23 at 10:36
Feel free to remove the parts from your answer that are not relevant. Afterward, please check whether the remaining answer is already part of https://stackoverflow.com/questions/32750250/tell-composer-to-use-different-php-version - there's no need to duplicate answers – Nico Haase Jun 01 '23 at 10:43
Changing the Apache part won’t help in getting composer to use the PHP version. Setting php82 as the alternative should do the trick. – Danny Van Der Sluijs Jun 01 '23 at 16:31
