<para>
For tar-based phar archives, this method compresses the entire archive using
gzip compression. The resulting file can be processed with the gunzip command, or
accessed directly and transparently with the Phar extension.
</para>
<para>
For Zip-based and phar-based phar archives, this method compresses all files in the
Phar archive using gzip compression.
The <link linkend="ref.zlib">zlib</link> extension must be enabled to take
advantage of this feature. In addition, if any files are already compressed using
bzip2 compression, the <link linkend="ref.bzip2">bzip2</link> extension must be
enabled in order to decompress the files prior to re-compressing with gzip 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.
