building an array of files

Hello folks -

I'm working on a function to map a php project that's gotten a little
unwieldly. I'd like to have a reference of all files like the output
of the unix tree command, like this:
..
|-- index.php
| |-- menu.php
| |-- content.php
| |-- admin_page.php
| | |-- admin_function1.php.inc
| | |-- admin_function2.php.inc
| | |-- admin_function3.php.inc
| | `-- admin_subpage.php
| | |-- admin_subfunction1.php.inc
| | |-- admin_subfunction1.php.inc
| | `-- admin_subfunction1.php.inc
| `-- user_page.php
| |-- user_function1.php.inc
| |-- user_function2.php.inc
| |-- user_function3.php.inc
| `-- user_subpage.php
| |-- user_subfunction1.php.inc
| |-- user_subfunction1.php.inc
| `-- user_subfunction1.php.inc
|
|-- orphan_page.php
`-- deprecated_page.php

I have a function that can create such text output ( or close enough )
from an array structure like this:

Array (
[0] => ./index.php
[1] => Array (
[0] => ./clients.php
[1] => Array (
[0] => ./login_function.inc
[1] => ./client.php
[2] => ./client_new.php
[3] => ./client_edit.php
)
[2] => ./inventory.php
[3] => Array (
[0] => ./login_function.inc
[1] => ./inventory_item_add.php
[2] => ./inventory_item_remove.php
)

[4] => ./daily_report.php
[5] => ./weekly_report.php
[6] => ./monthly_report.php
[7] => ./catalog.php
[8] => Array (
[0] => ./login_function.inc
[1] => ./catalog_item_add.php
[2] => ./catalog_item_remove.php
)
[9] => ./orders.php
[10] => Array (
[0] => ./login_function.inc
[1] => ./view_order.php
[2] => ./order_new.php
[3] => ./order_edit.php
)
[11] => ./invoices.php
[12] => Array (
[0] => ./login_function.inc
[1] => ./view_invoice.php
[2] => ./invoice_new.php
[3] => ./invoice_edit.php
[4] => ./invoice_print.php
[5] => ./invoice_email.php
)
)
[2] => ./clients_old.php
[3] => ./old_inventory.php



However, now I'm having a problem building the array of files!

Starting with a default root file, index.php, I can loop through each
file and find each .php or .inc file. Then I can create an array like

Array (
[0] => ./index.php
[1] => Array (
[0] => ./clients.php
[2] => ./inventory.php
[4] => ./daily_report.php
[5] => ./weekly_report.php
[6] => ./monthly_report.php
[7] => ./catalog.php
[9] => ./orders.php
[11] => ./invoices.php
[2] => ./clients_old.php
[3] => ./old_inventory.php
)

Then, I need to go through each element and find out what files are
referenced in that file, and insert that array. So I would get:

Array (
[0] => ./index.php
[1] => Array (
[0] => ./clients.php
[1] => Array (
[0] => ./login_function.inc
[1] => ./client.php

However, I'm having problems getting started. What function can I use
to insert an array at a certain point?

There isn't really a straightforward way to insert an element at some
arbitrary position in an array. You can split the array in two and
then stitch it back together with something in the middle.

Instead of processing your files level by level, why not do it
recursively? For instance, when your parse index.php, instead of
adding clients.php, then inventory.php, and then going back and
checking for their includes, add clients.php and check for his
includes. When that's done, add inventory.php and check for his
includes. That way you never need to insert the new array in the
middle of the parent -- it'll just happen in the right order the first
time.

Or store the info as XML and use XPath.... The first bit of work would
be harder, but then all the lookups and stuff would be there for you.

And you really don't have to care where the stuff is in the tree - just
look it up every time and add child nodes.
