   * guaranteed to work in both SAPI and non-SAPI environments.
   * Implementations must determine which environment they are in, and use the
   * appropriate method (move_uploaded_file(), rename(), or a stream
   * operation) to perform the operation.
   *
   * $targetPath may be an absolute path, or a relative path. If it is a
   * relative path, resolution should be the same as used by PHP's rename()
   * function.
   *
   * The original file or stream MUST be removed on completion.
   *
   * If this method is called more than once, any subsequent calls MUST raise
   * an exception.
   *
   * When used in an SAPI environment where $_FILES is populated, when writing
   * files via moveTo(), is_uploaded_file() and move_uploaded_file() SHOULD be
   * used to ensure permissions and upload status are verified correctly.
   *
   * If you wish to move to a stream, use getStream(), as SAPI operations
   * cannot guarantee writing to stream destinations.
