<para>
For tar-based phar archives, this method throws a
<classname>BadMethodCallException</classname>, as compression of individual
files within a tar archive is not supported by the file format. Use
<function>Phar::compress</function> to compress an entire tar-based phar archive.
</para>
<para>
For Zip-based and phar-based phar archives, this method decompresses all files in the
Phar archive.
The <link linkend="ref.zlib">zlib</link> or <link linkend="ref.bzip2">bzip2</link>
extensions must be enabled to take advantage of this feature if any files
are compressed using bzip2/zlib compression.
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.

bzip2 compression and the <link linkend="ref.bzip2">bzip2</link> extension
