title: associative to numeric array in PHP
body: <p>I have an associative array, which keys I want to use in numbers. What I mean: The array is kinda like this: </p>
  
  <pre><code>$countries = array
      "AD"  =&gt;  array("AND", "Andorra"),
      "BG"  =&gt;  array("BGR", "Bulgaria")
  );
  </code></pre>
  
  <p>Obviously AD is 0 and BG is 1, but when I print <code>$countries[1]</code> it doesn't display even <code>"Array"</code>.
  When I print <code>$countries[1][0]</code> it also doesn't display anything. I have the number of the key, but I shouldn't use the associative key.</p>
