如何更改作曲家使用的PHP版本 [英] How to change PHP version used by composer

问题描述

除了要使用WAMP (2 PHP version installed)已安装的版本外，我想在我的计算机上使用另一个版本的php.

I want to use another php version on my machine than the one already installed using WAMP (2 PHP version installed).

• 安装的作曲家使用PHP 5.6
• 新项目需要PHP7.0.

• The composer installed uses PHP 5.6
• A new project requires PHP7.0.

每当我从WAMP的控制面板中选择PHP 7，然后运行php -v时，它仍会打印PHP5.6 (CLI)...而不是PHP7.

Whenever I choose PHP 7 from the control panel of WAMP and then run php -v it still printing PHP5.6 (CLI)... instead of PHP7.

如何在不重新安装作曲家的情况下使用PHP7?

How can I use PHP7 without reinstalling the composer again?
