var_dump() is function you are looking for.
var_export() exports variables to a parsaable strings, but resources
cannot be represented as strings due to their nature.

Description:
------------
A simple mysql_connect() returned NULL for this particular
configuration of PHP:
--with-mysql=/usr/lib/mysql
--with-mysql-sock=/var/run/mysqld/mysqld.sock
--with-mysqli=/usr/bin/mysql_config
--with-pdo-mysql=/usr
When the script is ran with wrong login credentials, mysql_connect()
returns false as documented. However, when everything checks out no
errors are thrown and NULL is returned instead of a resource.
This is not documented behaviour as far as I know ;-)
Reproduce code:
---------------
<?php
error_reporting(E_STRICT);
$r = mysql_connect('localhost','user','pw');
var_export($r);
?>
Expected result:
----------------
"Resource #1" (or something similar)
Actual result:
--------------
"NULL"
A strace on the process returns the following:
