PHP filesystem access functionality

folders/directories and file metadata

PHP's functionality for managing folders is a mix of classes and standalone functions.

To get a directory listing:

«dir()» accepts a filepath to an existing folder and returns a «Directory» object.
«glob()» accepts a filespec that includes a file mask, and returns a list of matching filespecs.
- A file mask in this context can be e.g. «*.php» or «/home/woozle/*.php» but not «~/*.php».
- The «*» and «?» wildcards are both recognized.
- The mask may include multiple wildcards, for folders as well as files. Example: «/b*/b*» will return all files beginning with b inside root-level folders beginning with b.

To parse a filespec:
