[Config4gnu-developer] proposed changes to PHP mod

[Jason L. <jl...@me...>]

Justin here are some proposed modifications to the PHP extension. This will
give you an opportunity to work with the new PHP code.

Modifications will be made to src/clients/php/zendmod.c

1. Change name of c4g_get_top_node to c4g_get_root_node. Since we are using
a tree hierarchy, I think this name would make more sense.

2. Take the code that actually reads the top node from c4g_get_top_node and
put it in the `module_init' function. Create a module-level static variable
to hold the top node after initialization is complete and use it in the
`c4g_get_top_node' function instead of loading a new tree.

If you look at the PHP manual, you'll notice that chapters 24-42 talk about
extending PHP. You may want to read them.
