title: PHP & URL Rewriting
body: <p>I need a little help figuring out what the following URL rewrite rule means. I can understant the first three lines, but I got stuck with the <code>index.php/$1</code> part. What does exactly the <code>/</code> means in this rule? The only thing I would always expect to see after a file name would be a query-string separator (<code>?</code>). This is the first time I am seeing the <code>/</code> as a separator. What does it exactly mean?</p>
  
  <pre><code>&lt;IfModule mod_rewrite.c&gt;
      RewriteEngine On
  
      RewriteCond %{REQUEST_FILENAME} !-f
      RewriteCond %{REQUEST_FILENAME} !-d
  
      RewriteRule ^(.*)$ index.php/$1 [PT,L]     
  &lt;/IfModule&gt;
  </code></pre>
