When var_export is called on an object which has another object as one of its members, it does not produce valid code.

Reproduce code:
$a->b = 1;
eval(var_export($a, 1) . ';');

Actual result:
Fatal error: Cannot redeclare class stdclass in test.php(3) : eval()'d code on line 1

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.
