The following should result in a parse error:

  $foo = 'bar';
  $bar = 'hello';

  print $      $foo; // hello
  print $$foo;       // hello

Instead, 'hello' is printed both times.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

This isn't a bug but how PHP has always worked.
Changing this behavior isn't really feasible because of the way the parser works. I do suggest however that you use $$foo because the spaces are pretty ugly.

It's not a bug but it's a little weird, that's all :)
