Determine the framework used from a website source dump
<p>I don't know if this is the right place to ask a question like this, but it is programming related, so here goes.</p>

<p>I was given a zip file containing the entire source data for a website, including the scripts used to create the database backing it. I know that the site was built using a PHP-based framework, but not which one. I was asked to gain some basic familiarity with the structure of the site, and be able to make at least small changes to the UI.</p>

<p>The problem I have is that I don't recognize the framework used, although I'm pretty sure that the site was built using one. I know it isn't Zend, but that's about it.</p>

<p>The question is, what would you look for from the source in order to determine the technology used to create a site, given the product?</p>
