title: Reference to file regardless of the folder structure and depth
body: <p>My research has lead me to believe that it <strong>might</strong> be called, <strong>absolute URL / relative URL</strong>. But please, I am not sure. So this is not reason to give me a minus as I have just reached 50 and I am on a STEEP learning curve.</p>
  
  <p>In my index.php</p>
  
  <p>I have a reference to a csv array. <code>/array/test.csv</code></p>
  
  <p>Then, I have a folder called <strong>MENU</strong>. In this folder I have a PHP called menu.php which also needs to make reference to the test.csv. However I <strong>Cannot</strong> put <code>/array/test.csv</code>, instead I have to put <code>../array/test.csv</code>.</p>
  
  <p>So depending where you are in a folder structure, you might have to use <code>/ or ../ or ../../</code>,</p>
  
  <p>Can someone point out the correct way to do this as I know that I will have problem if I do not learn the correct way.</p>
