Planned PHP function support for the Runtime for PHP

The PHP language has an extensive set of functions available to be used by anyone developing a PHP application. Project Zero currently supports the PHP language and a subset of the popular functions. More functions are being added all the time. To see the currently implemented list look at the list of Core PHP functions.

This page shows the PHP functions we intend to support over the coming months. Look for the function category in the list of planned enhancements for the next milestone and then see the list of functions in the table below. Note that the priority of these functions can change as we receive feedback from users. And we may implement some other functions not in this list if we find they make sense to implement at the same time as another one.
