PHP filesystem access functionality
folders/directories and file metadata

About

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:

  • «basename()» returns the last element of a filespec, with some options.
  • «dirname()» returns the filepath to the given file/folder's parent folder.
  • «pathinfo()» breaks a filespec down into multiple components.
  • «realpath()» returns a de-contextualized canonical absolute filespec.
