title: PHP HTTP-Request
body: <p>I have MAMP Pro installed running php 5.2.13. When I try to initialize a HTTP-Request </p>
  
  <pre><code>$r = new HttpRequest('http://example.com/', HttpRequest::METH_GET);
  </code></pre>
  
  <p>it tells me:</p>
  
  <blockquote>
    <p>"Class 'HttpRequest' not found in ...". </p>
  </blockquote>
  
  <p>What do I need to do to 'install(?)' it?</p>
