title: Using PHP Namespaces
body: <p>I have been searching websites to try and get a handle on using PHP namespaces, but they all seem quite vague but what they're trying to do is easy to understand!</p>
  
  <p>My question is: I have a file called <code>people.php</code> and in it is defined class called <code>people</code>. If I create another file called <code>managers.php</code> in the same folder can I define a class again called <code>people</code> which extends the original <code>people</code> class but in the namespace of <code>managers</code>, if so do I have to 'include' the original <code>people.php</code> and if so do I put the include after the writing: <code>namespace managers</code>?</p>
