   that cannot be represented with existing information stored with a file.
   Meta-data can significantly slow down the performance of loading a phar
   archive if the data is large, or if there are many files containing meta-data.
   It is important to note that file permissions are natively supported inside a
   phar, although it is possible to set them with the
   <A
HREF="function.pharfileinfo-chmod.html"
><B
CLASS="function"
>PharFileInfo-&#62;chmod()</B
></A
>
   method.  As with all functionality that modifies the contents of a phar, the
   <A
HREF="ref.phar.html#ini.phar.readonly"
>phar.readonly</A
> INI variable must be
   off in order to succeed.
  </P
><P
>&#13;   Some possible uses for meta-data include passing a user/group that should be set
   when a file is extracted from the phar to disk.  Other uses could include
   explicitly specifying a MIME type to return.  However, any useful data that
   describes a file, but should not be contained inside of it may be stored.
