How to install all required PHP extensions for Laravel?
<p>I need to make my Ubuntu 16.04. Is there a way using the GUI or is the simplest way to do this by using terminal?</p>

<p>I have already installed PHP 7.1, MariaDB.</p>

<p>I need to enable:</p>

<ol>
<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>
</ol>
