Class to handle file searching.

Variables

$relative_path

If not null, it is the file system path that all paths are attempted to resolve to. If null, all resolved paths are absolute @protected static string $relative_path

$relative_root

The root drive of the relative path e.g. "C:" on windows or '/' on unix. on windows unix it may or may not contains the trailing "\" due to the following maddness: *realpath(C:) is C:\ *realpath(C:\) is C:\ *realpath(C:\\) is C:\ *realpath(C:\some) is C:\some *realpath(C:\some\) is C:\some @protected static string $relative_root

$relative_parts

The parts of the relative path. On windows, it does not include the drive letter. @protected static array of string $relative_parts

$found_locales

The found locale(s) . One of: FALSE, a string, or an array. The former two in the case of a single serach, the later in case of a $find_all search

$preferred_locales

. Keys are categories. Values are arrrays of string, the preferred locales.

$ordered_paths

$absolut

protected $var boolean $absolut -- wheter or not to make relative paths absolut based on the directory of the calling file

$search_hidden

protected $var boolean $search_hidden. Whether or not to search hidden sub-directories

$search_cwd

protected @var boolean $search_cwd. Whether or not to seach the current working directory

$last_order

protected @var array $last_order values are the order of the last thing added to the category keys are the classes.

$checked_directories

protected @var array $checked_directories array with keys directories and values boolean It is true if the directory has already been checked. Used to avoid recursion,

Methods

__construct()

Constructor for the FileSearch class

  • Signature: public function __construct($hidden,$current_working,$make_absolut)
  • Parameters:
    • boolean $hidden
      Defaults to false. Whether or not to search hidden sub-directories. At the moment it does not have meaning on non unix like platforms.
      • Default Value: false
    • boolean $current_working
      Defaults to false. Whether or not to search the current working directory for the file. If so, it checks there first, before the other paths.
      • Default Value: false
    • boolean $make_absolut
      Defaults to false. Whether or not to make a relative path absolute when adding it.
      • Default Value: false

      of string. The keys are the paths we want to search, the values are the locale they are in
    • boolean $find_all
      If true we find all files, otherwise we return on the first match

absolut()

Makes a relative file path or file url absolute relative to the directory that the function was called in.

  • Defined in i2ce/lib/I2CE_FileSearch.php on line 415
  • Signature: static public function absolut($path,$indx)
  • Parameters:
    • string $path
      a path or URL
    • int $indx
      the index, from the top level, to consider the calling file defaults to 0 which is the file that is calling this.
      • Default Value: 0
  • Returns: string
    the absolute path or URL

addPath()

A path to search for a category of files.

  • Defined in i2ce/lib/I2CE_FileSearch.php on line 580
  • Signature: public function addPath($category,$path,$order,$absolut,$path_prefix,$locales)
  • Parameters:
    • string $category
      the category of files.
    • string $path
      the parh (or glob pattern for a path) to add. There a a few modifications to the globbing... A trailing '**' means that the paths should be added recursivley Paths are automatically checked for localized version by the presence of a 'en_US' subdirectory. specifically, if a path is added such as /my/path and there is a subdir called /my/path/en_US then all subdirectories which are in the preffered locales (or $locales below) are added. Examples: /usr/share/fonts/ adds in this directory to the search paths /usr/share/fonts/* adds in all subdirectories /usr/share/fonts/** recusively adds in all subdirecties /usr/share/fonts/truetype/ttf* adds in all directories begining with ttf
    • mixed $order
      If it is a number, then it indicates the order in which this path is searched. The lower the number, the higher the priority. If multiple paths share the same order, the order in which they are searched is not specfied The are also special string values of $order (all are relative to the category specified):
      • 'LAST' -- add at the last added order
      • 'LOWEST' -- add so it has the lowest order thus far
      • 'HIGHEST' -- add so it has the highest order thus far
      • 'EVEN_LOWER' -- add so it has lower order than anything thus far. This is the default behavior
      • 'EVEN_HIGHER' -- add so it has higher order than anything thus far
      • Default Value: 'EVEN_LOWER'
    • boolean $absolut
      whether or not to try to make a relative path absolut. It will overide (but not change) the global behaviour of this instance.
      • Default Value: null
    • string $path_prefix
      Defaults to null. Any prefix to add to a local class path (if we do make absolute)
      • Default Value: null
    • mixed $locales
      null(default) , string or array of string. Used to override the default locale settings when not the defaults of null. It is the list of localized sub-directories to search for, if the given glob is a subdirectory.
