<para>
|
|
<function>setMetaData</function> should only be used to store customized data in a file
|
|
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; it is possible to set them with the
|
|
<function>PharFileInfo->chmod</function> method. As with all
|
|
functionality that modifies the contents of a phar, the
|
|
<link linkend="ini.phar.readonly">phar.readonly</link> INI variable must be
|
|
off in order to succeed.
|
|
</para>
|
|
<para>
|
|
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.
