我已經安裝了 PHP 7.3.33、composer 1.1 并運行了多個 laravel 7.x 專案。
現在我正在嘗試安裝兩個不同的 Laravel 專案。一個使用 Laravel 9，另一個使用 7.x。
如果我更新 PHP 和 Composer 版本，它將在現有的 laravel 7.x 專案中產生問題。
有什么方法可以升級/使舊的 laravel 專案兼容 composer 2 和新的 PHP 版本。

您需要為 laravel 9 創建一個新環境，因為它與 php 7 不兼容。您可以使用 dockerLaravel sail 或 Virtual Machine來完成Laravel homestead。
如果您使用的是production environment，我建議您使用另一個服務器實體或部署在容器中。在其他方面，您也可以將 PHP-FPM 與 Apache / Nginx 一起使用。
如果您正在使用Local environment并且不了解管理系統/devops，您可以使用Laragon或Wamp安裝不同版本的 PHP

我在 Windows 上，我如何解決這個問題是通過下載我想要的 PHP 版本并將它們放在同一目錄中的檔案夾中。里面parent folder我有php72 php74 php8。
然后我在終端中編輯路徑位置并指向同一個檔案夾，但是我參考了該檔案夾php。
假設在我的目錄中我有php72 php74 php8并且我希望使用php8我會將該檔案夾重命名為php
現在我的目錄看起來像這樣php72 php74 php
如果我需要更改為 php72，我將重命名目錄如下
php php74 php8
我也為作曲家實作了類似的解決方案
這是一種有點奇怪的 hacky 方式，但是它很容易實作并且對我有用，希望它也對你有用。

這是因為在您的 composer.json 檔案中的專案中，您有：
"require": {
"php": "^7.4",
.....
},
嘗試將此要求更新為：
"require": {
"php": "^7.4|^8.0",
.....
},
或者，如果您不安裝任何新版本的 PHP，您可以這樣做。它將忽略請求。
composer install --ignore-platform-reqs
