Description:
------------
A limitation of var_export() is not documented. It does not support resources. The manual says "generated valid PHP code" which is fine. But it should be noted that resources are not supported, i.e. they're not reflected as resources in var_export anymore.

Reproduce code:
---------------
$ php -r '$f = fopen("/", "r"); var_export($f);'
NULL

According to http://bugs.php.net/bug.php?id=29361 it also doesn't supported objects containing references to other objects. This should be documented too.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

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

"Variables of type resource and arrays or objects containing objects couldn't be exported by this function."

I am reopening this as I found a way to do this for classes now.
