title: Using Laravel on php 7.0
body: <p>I have installed Laravel 5.5 and I'm getting the same error, documentation says this:</p>
  
  <ul>
  <li>PHP >= 7.0.0</li>
  <li>OpenSSL PHP Extension</li>
  <li>PDO PHP Extension</li>
  <li>Mbstring PHP Extension</li>
  <li>Tokenizer PHP Extension</li>
  <li>XML PHP Extension</li>
  </ul>
  
  <p>I ran:
  <code>
  $ php artisan --version`
  $ Laravel Framework 5.5.42
  </code></p>
  
  <p>and I'm getting this error:</p>
  
  <p><code>
  Symfony \ Component \ Debug \ Exception \ FatalThrowableError (E_PARSE)
  Parse error: syntax error, unexpected '?', expecting variable (T_VARIABLE)
  </code></p>
  
  <p>Is the documentation wrong? I'm using: <a href="https://laravel.com/docs/5.5/installation#installing-laravel" rel="nofollow noreferrer">https://laravel.com/docs/5.5/installation#installing-laravel</a>
  My server can only use PHP 7.0. Not 7.1. Is there no way to run Laravel on 7 anymore?</p>
  
  <p>I'm installing via composer.</p>
  
  <p>Is there a way to download a compatible version with 7.0?</p>
