Composer创建项目问题

Question

I am getting the following error while creating project

C:\MAMP\htdocs>composer create-project laravel/laravel testing 5.2

Your version of PHP, 5.4.1, is affected by CVE-2013-6420 and cannot safely perform certificate validation, we strongly suggest you upgrade.

Answer 1

This means that your version of PHP is too old and has known vulnerabilities. You should upgrade the PHP version to at least 5.6, but I would recommand to upgrade directly to 7.0 or 7.1. They are under active support (until dec 3rd for 7.0) and have better perfomance.

Moreover laravel 5.2 needs a PHP version >= 5.5.9. It's written in the requirements.

Here is the supported version chart of PHP. You shouldn't use any version that is in red.
