安装Laravel所需的最低php版本

What's the minimum php version required to install Laravel? According to this wikihow tutorial, the minimum version required is 6.3.7:

Install Laravel Framework in Windows *PHP version greater than 6.3.7 is required.

But the latest php version that can be installed with xampp is 5.6.3. If a grater version is required, how can I install it?

Wikihow is wrong. The requirements for Laravel 4.2 are:

• PHP >= 5.4
• MCrypt PHP Extension

Laravel Docs

By the way, for Laravel 5, the (not final) documentation states:

• PHP >= 5.4
• Mcrypt PHP Extension
• OpenSSL PHP Extension
• Mbstring PHP Extension
