A similar, perhaps identical problem also occurs with arrays that contain objects. In that case the code produced by var_export causes an unexpected T_CLASS parse error.

Here's the code produced by var_export for the array with an object:
array (
  0 => 
  class myclass {
    var $myProperty = 'myValue';
  },
);

THere is no way how this can be fixed; if you can think of something how this should work, please provide a patch.

I found a way myself now, assigning.

Thank you for the report, and for helping us make PHP better.

Fixed for PHP 5.1.0 and 6.0.0 (and higher).
