This test script gets rid of the RecursiveIteratorIterator, and focuses only on the RecursiveArrayIterator.

Perhaps you have already faced with that too, that method chaining fails even with stdClass. If not than this script provides an example:

Hello again,

I would like to offer my help with some simple test scripts, which will be collected at

https://github.com/namarpi/PHP-SPL-Recursive-Examples

If you need them use them.

Hello,

good news: method chaining works (leastwise two levels), so apology for the rumor. Here is the script which contains two solutions, one for RecursiveIteratorIterator, and one for RecursiveArrayIterator. It would be really nice to complete this wiki page: http://en.wikipedia.org/wiki/Method_chaining :))

I think it might be interesting:

Manual says: public void ArrayIterator::offsetSet ( string $index , string $newval )
but thank to Developer it works with offsetSet ( string $index , array/stdClass $newnode ) too.

https://github.com/namarpi/php-reports/blob/master/offsetSet-string-and-array.php

I would like to insert new nodes into the array with iterator, but the solutions in the previously linked test script were not consistent. So, found a better way to insert and modify new nodes dynamically, and append them to the iterator on the fly. This works so smooth and nice that it must be a good solution in the case of stdClass.

Hi,

grateful thanks for your offer with the test scripts. I think it had much more sense to turn your scripts into teh phpt test cases and then do a PR on github. Please see http://qa.php.net/howtohelp.php for how to write test cases, and please  reduce the test code to the absolute required minimum. The smaller the repro code is, the easier it is to debug errors.

Cheers
