title: How to make a Cascading Drop Down List in PHP using jQuery
body: <p>I have database consists of countries and cities.</p>
  
  <p>First Case - Successfully done:</p>
  
  <ol>
  <li>Country list gets populated in drop box on page load</li>
  <li>City list gets populated in drop box on page load - populated city list
  is based on the default country.</li>
  </ol>
  
  <p>Second Case - Couldn't make it:</p>
  
  <ol>
  <li>User changes country</li>
  <li>City list will be changed according to selected country</li>
  </ol>
  
  <p>I know i have to use jQuery/Ajax. I tried but i couldn't solve my problem due to my lack of programming experience. My list is fetched from database not XML. I just need a quick solution, i need to keep it simple and stupid.</p>
  
  <p>I'm using regular PHP coding style, not Object-Oriented.</p>
  
  <p>How can i do it? Any related resources will be appreciated.</p>
