 /**
  * Creates a PHAR (PHP Archive) file from an entire directory.
  *
  * @param string       $dir The directory we want to create a PHAR file for.
  *
  * @param string       $to The new PHAR file location; with a `.phar` extension.
  *
  * @param string       $stub_file Stub file path. The contents of this stub file will be used as
  *    the stub for the resulting PHAR file. Required for all PHARs created by this routine.
  *    A final call to `__HALT_COMPILER();` is automatically appended by this routine.
  *
  * @param boolean      $strip_ws Optional. Defaults to a TRUE value (highly recommended).
  *    If this is TRUE; any PHP files in the archive will be further reduced in filesize by this routine.
  *    This is made possible by the `php_strip_whitespace()` function.
  *
  * @param boolean      $compress Optional. Defaults to a TRUE value (highly recommended).
  *    If this is TRUE; any compressable files in the archive will be further reduced in filesize.
  *
  * @param string|array $compressable_extensions Optional. An array of GZIP-compressable extensions.
  *    This will default to only those which are 100% webPhar-compatible: `array('php', 'phps')`.
  *    Or, you can provide your own array of compressable extensions.
  *
  * @param string       $is_phar_var_suffix Optional. Defaults to `stub`.
  *    A global variable at the top of your PHAR stub file will be declared as follows.
  *    `$GLOBALS['is_phar_'.$is_phar_var_suffix] = 'phar://'.__FILE__;` (just a helpful identifier).
  *
  * @return string The new PHAR file path; else an exception is thrown on any type of failure.
  *
  * @throws exception If invalid types are passed through arguments list.
  * @throws exception If `$dir` is empty, does NOT exist; or is NOT readable for any reason.
  * @throws exception If `$to` is empty, or is NOT specified with a `.phar` extension.
  * @throws exception If `$to` parent directory does NOT exist; or is not writable.
  * @throws exception If `$stub_file` is empty, does NOT exist; or is NOT readable for any reason.
  * @throws exception If `$compressable_extensions` or `$is_phar_var_suffix` is empty.
  * @throws \exception If any Phar class failures occur. The Phar class may throw exceptions.
  * @throws exception On any type of failure (e.g. NOT successful).
  *
  * @WARNING This routine can become resource intensive on large directories.
  *    Mostly because of the compression routines applied here intuitively. It takes some time.
  *    See: {@link env::maximize_time_memory_limits()}
