Hey, welcome to the Structure_Linked_List package for PHP.
This package requires PHP 5, and was primarily developed with PHP 5.1.4. I have also successfully tested 5.2.0RC2.
Read the Structure_Linked_List API documentation -- let me know if the API has what you need, or if you want more documentation.
Comments are welcome by email at firstname.lastname@example.org.
I plan to add more defensive code (for example, check class type of objects passed to the Structure_Linked_List_Node constructor), add more unit tests, flesh out the documentation, and try to find any missing functionality that needs to be implemented before submitting this as a PEAR proposal. I'm aiming for sometime in September.
Sorry for the really raw HTML here... for me it's all about substance first, and style later.
