Request #53659 Implementing RegexIterator::getRegex() method

I'd like to see an getRegex() method in the regexIterator class that will return the regular expression that is initialized during its __construct(). 

Currently there is no way of retrieving that information except for saving it yourself outside the object or extending regexiterator in order to save the regex inside a custom constructor. 

It would be nice if the information about the object could actually be retrieved natively since this data is already present, just not visible to the outside world.

Attached is a patch with an implementation.  

Test script:
$array = array('cat', 'hat', 'sat');
$iterator = new ArrayIterator($array);
$regexIterator = new RegexIterator($iterator, '/.at/');

Expected result:
string(5) "/.at/"

Actual result:
PHP Fatal error:  Call to undefined method ArrayIterator::getRegex()

Looks good at a first pass. Let's see about getting it into trunk.

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

Committed on trunk: the change to the _spl_dual_it_object struct will
prevent this going into 5.3. Thanks for the patch, Joshua!
