function pleac_Removing_a_Directory_and_Its_Contents()
{
    // AFAICT, there is currently no library function that recursively removes a
    // directory tree [i.e. a directory, it's subdirectories, and any other files]
    // with a single call. Such a function needs to be custom built. PHP tools
    // with which to do this:
    // * 'unlink', 'rmdir', 'is_dir', and 'is_file' functions, will all take care
    //   of the file testing and deletion
    // * Actual directory traversal requires obtaining directory / subdirectory
    //   lists, and here there is much choice available, though care must be taken
    //   as each has it's own quirks
    //   - 'opendir', 'readdir', 'closedir'
    //   - 'scandir'
    //   - 'glob'
    //   - SPL 'directory iterator' classes [newish / experimental - not shown here]
    //
    // The PHP documentation for 'rmdir' contains several examples, each illustrating
    // one of each approach; the example shown here is loosely based on one of these
    // examples
    // Recursor - recursively traverses directory tree
