I don't believe this is a bug as the purposes of var_dump and var_export are
entirely different:
var_dump - simply dumps a readable form
var_export - exports valid PHP! This code is actually usable within an
application.
var_dump therefore can "manage" the recursive nature of global by simply doing
the following in the output
&array(15) {
["GLOBALS"]=>
*RECURSION*
var_export on the other hand clearly can't take the same approach to recursion
if the generated PHP output is to work as intended by the application designer.
- it can only (and should only) fail.
hope this is useful to someone.

This bug is VALID!
The following code works:
var_dump($GLOBALS);
Therefore the dumping algorithm is inconsistent. var_export() should just use
the same algorithm as var_dump().

Derick, I'd suggest that that "expected behavior" itself is a design flaw in
the
PHP interpreter. The solutions I can think of right off would be ugly, granted
(special-case check for global-variable accessor to detect whether it's
attempting
to recurse as an effect of debug_backtrace() and, if so, throw an exception
that
can then be caught by d_bt); I find it really hard to believe that such a
heavily-
used software platform with such a large, competent company and community
behind
it can't come up with a better solution.
Marking this bug as 'bogus' merely insults your developer customers and
encourages
them to go find a real language instead.

There is no way to return a correct output in this case, so this is not a bug
but expected behavior.

Description:
------------
doing var_export( $GLOBALS, true ) there is an error
like in older versions of php4:
Nesting level too deep - recursive dependency?
Of course it is easy to do a workaround, but maybe it
would be nice to fix it. Theres a lot of discussion
araound this bug in some communities for older php
versions. Maybe it is me being in error or maybe this is
just a feature and not a bug? In this case sorry for
disturbing...
Thanks a lot for all your work!
Reproduce code:
---------------
<?php
$outText = var_export( $GLOBALS, true );
?>
Expected result:
----------------
I would expect to get var_export in $outText
Actual result:
--------------
array ( 'GLOBALS' => array ( 'GLOBALS' => array (
'GLOBALS' => array (
Fatal error: Nesting level too deep - recursive
dependency?
