On a related note, outside of strings one should always surround keys with
quotes, so:

  $arr = array('a' => 'apple', 'b' => 'banana');

  print $arr['a']; // apple
  print $arr[a];   // apple BUT this is bad

Without the quotes is bad because PHP first:

  a) looks for the constant named 'a'
  b) if constant 'a' is not found, an error of type 
     E_NOTICE is thrown.

So, let's do this:


  print $arr['a']; // apple
  print $arr[a];   // banana (no error)

Because constants are not looked for within strings, the following is

  print "an $arr[a]";     // an apple

As are:

  print "an {$arr['a']}"; // an apple
  print "an ". $arr['a']; // an apple

Anyway, maybe that helps explain a few things :)
