Iterators in PHP

Recently, while playing with Scala/Python/PHP comparative implementation of lazy algorithms (I will hopefully describe them some days later) with colleague and friend of mine Michael Fuks, I sorrowfully discovered that, despite there are several SPL units, which define basic Iterator interfaces and functionality, most of the functionality available for arrays is missing for Iterators.

So I decided to fill the gap and started to reimplement for Iterators the applicable non-trivial array functions and also started trying to simulate iterator comprehension (generator routines) in PHP which is missing there too. For this reason I opened a GoogleCode project of php-iterator-utils – please observe my first experiments here.

In addition I need to notice that latest NetBeans build (6.8) branch has great PHP 5.3 support and feels more stable, fast and functional than Eclipse PDT 😦
