PHP: Two basic questions about URL
<p><strong>Question 1</strong></p>

<p>www.example.com/<strong>?do=blah</strong></p>

<p>How do you get it to work without index.php? Any examples?</p>

<p><strong>Question 2</strong></p>

<p>www.example.com/news.php?blah</p>

<p>This link doesn't show the same result as news.php, but shouldn't we be using news.php&amp;blah=value for example? What does the string after ? stand for? Shortened version of GET variables or an entirely different thing?</p>
