View source for Re: Plugins Directory

Not sure why it needs ##$checkIfFileExists## at all, if it checks only for the path and not the file.

  * ##explode()## consumes less resources.
  * The function itself should be placed in Ut class, e.g. ##Ut::join_multi_path()##
  * Perhaps it is better to mirror the folder structure by just set the ##'plugin'## folder as prefix in the function
    * ##const PLUGIN_DIR = 'plugin'##,
    * ##$paths =  [PLUGIN_DIR . '/' . $path, $path]##
