title: How to import libraries in PHP
body: <p>I am normally an ASP.NET developer who wants to migrate to PHP. I am taking quite a time to learn it and I am wondering how to use libraries in PHP?</p>
  
  <p>Do I need to use <code>require</code> or <code>include</code> to import a library into my project to use the <code>classes</code>, <code>functions</code> etc. defined in the library? Or something else.</p>
  
  <p>I running PHP on the Apache web server what I've found is for Zend Server and it looked weird to me.</p>
  
  <p>Can someone explain me overall steps to import and start using libraries in my own code?</p>
  
  <p>Thanks.</p>
