title: How to take PHP input parameter from URL like this www.domain.com/item/ABC123
body: <p>I the want user to visit www.domain.com/item/ABC123 </p>
  
  <hr>
  
  <p>As you can see here ABC123 should be the input parameter</p>
  
  <p>like this www.domain.com/item/?Id=ABC123 </p>
  
  <p>Under /item/ there is an index.php file, that will take an Id input parameter, how do I pass the input parameter value from www.domain.com/item/ABC123 to the id input parameter of the index.php file?</p>
