PHP filespec wildcard matching & searching

aka "globbing"

PHP can do glob-based directory listings and can also check a given filename string against a given glob string.

«fnmatch()» reports whether the given filespec string matches the given wildcard string
«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.
