Link url my site
<p>I have a site with 2 languages that are En and kh. Each language has the same file name in different folder, i.e. /en/ and /th/. I've created  tag to switch between these 2 languages on my included header file (php).</p>

<p>The question is how to get the current path wherever you are, and change folder name to en or kh? (If you are inside English Contact page, clicking kh will take you to Thai Contact page.)</p>

<p>How to link this Language in my site?</p>
