PHP Kohana::_files_changed方法代码示例

 /**
  * Searches for a file in the [Cascading Filesystem](kohana/files), and
  * returns the path to the file that has the highest precedence, so that it
  * can be included.
  *
  * When searching the "config", "messages", or "i18n" directories, or when
  * the `$array` flag is set to true, an array of all the files that match
  * that path in the [Cascading Filesystem](kohana/files) will be returned.
  * These files will return arrays which must be merged together.
  *
  * If no extension is given, the default extension (`EXT` set in
  * `index.php`) will be used.
  *
  *     // Returns an absolute path to views/template.php
  *     Kohana::find_file('views', 'template');
