php - Composer create project issue

Solution:

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.

Solution:

you need update your PHP version source : https://laravel.com/docs/5.2/releases so PHP 5.5.9 + for you :)

PHP 5.5.9+ Since PHP 5.4 will enter "end of life" in September and will no longer receive security updates from the PHP development team, Laravel 5.1 requires PHP 5.5.9 or greater. PHP 5.5.9 allows compatibility with the latest versions of popular PHP libraries such as Guzzle and the AWS SDK.
