  &phar.write;
  <para>
   This method is used to convert a phar archive to another file format.  For instance,
   it can be used to create a tar-based executable phar archive from a zip-based
   executable phar archive, or from an executable phar archive in the phar file format.  In
   addition, it can be used to apply whole-archive compression to a tar or phar-based
   archive.
  </para>
  <para>
   If no changes are specified, this method throws a <classname>BadMethodCallException</classname>.
  </para>
  <para>
   If successful, the method creates a new archive on disk and returns a <classname>Phar</classname>
   object.  The old archive is not removed from disk, and should be done manually after
   the process has finished.

       This parameter is used to override the default file extension for a
       converted archive.  Note that all zip- and tar-based phar archives must contain
       <literal>.phar</literal> in their file extension in order to be processed as a
       phar archive.
      </para>
      <para>
       If converting to a phar-based archive, the default extensions are
       <literal>.phar</literal>, <literal>.phar.gz</literal>, or <literal>.phar.bz2</literal>
       depending on the specified compression.  For tar-based phar archives, the
       default extensions are <literal>.phar.tar</literal>, <literal>.phar.tar.gz</literal>,
       and <literal>.phar.tar.bz2</literal>.  For zip-based phar archives, the
       default extension is <literal>.phar.zip</literal>.
