Updated Question
I want to upgrade only the PHP version for my Laravel project,
My Laravel Framework version is 6.20.19 and PHP version is 7.4,
now I want to upgrade only php version php 7.4 to PHP 8.1 for my current Laravel project, how can I do without upgrading the Laravel version?
I have configured PHP 8.1 in my Linux System and configured my Laravel 6.20 version project, and made some changes in composer.json.
"require": { "php": "^8.1", "laravel/framework": "^6.0", "barryvdh/laravel-dompdf": "^0.8.5", "fideloper/proxy": "^4.4", "laravel/helpers": "^1.3", "laravel/socialite": "^5.2", "laravel/tinker": "^2.5", "razorpay/razorpay": "^2.5", "twilio/sdk": "^6.16", "vanilla/js-connect-php": "^4.0", "facade/flare-client-php": "^1.5", "symfony/http-foundation": "^5.4", "symfony/mime": "^6.2|^7.0", "symfony/mailer": "^v6.3.0", "swiftmailer/swiftmailer": "^6.0" }, "require-dev": { "facade/ignition": "^1.4", "fzaninotto/faker": "^v1.9.2", "laravel/ui": "^1.0", "mockery/mockery": "^1.4", "nunomaduro/collision": "^3.0", "phpunit/phpunit": "^9.5" },
now run "composer update --with-all-dependencies" Output

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
@rushikesh93 You can use this command file which helps you to easy switch from one version to another version within second. So when you have to work on this old laravel version project just switch. https://github.com/vinugawade/s-php/blob/master/s-php
@hupp I have already changed the PHP version from PHP7.4 to PHP 8.1, but after the PHP version change and running the project, I get the above errors, these errors are displayed because the current Laravl version is not compatible with PHP8.2, but I don't want to upgrade my Laravel version and I want to Fix this error.
how can I do that? please guide me on this. Thanks.
@rushikesh93 That's would be impractical but still you want to do than you have to make change in its vendor core files. and use the new alternative functions and syntax as per php 8.1 But after that all fix you can't update any composer package, if you do it will may overwrite these changes and all errors came again
You can't run laravel 6 on php 8.x
