How do you break down a new project with an existing mega PHP site?
<p>I've got to dive into a very large PHP site and have my first client meeting today. All they gave me so far was the URL. </p>

<p>How do you guys go about gathering/structuring/documenting and preparing for a new project in a PHP environment? What things do you ask for up front?</p>

<p>PS - I know there are other general questions about this but I want a PHP-flavored one, including tools (even if universal) and approaches.</p>

<p>Thanks!! I'm excited but also scared.</p>
