How to access php variable using concatenation
<p>I want to access a variable that is either called <code>$item1</code>, <code>$item2</code> or <code>$item3</code>.  </p>

<p>I want to access this variable inside a for loop where <code>$i</code> is <code>++</code> every time.  using <code>$item.$i</code> or something similar.  However using  that code means that I am trying to join the contents of two variables, and there is no variable called $item.  </p>
