Phar::decompress — Decompresses the entire Phar archive
For tar-based and phar-based phar archives, this method decompresses the entire archive.
For Zip-based phar archives, this method fails with an exception. The zlib extension must be enabled to decompress an archive compressed with gzip compression, and the bzip2 extension must be enabled in order to decompress an archive compressed with bzip2 compression. As with all functionality that modifies the contents of a phar, the phar.readonly INI variable must be off in order to succeed.
In addition, this method automatically changes the file extension of the archive, .phar by default for phar archives, or .phar.tar for tar-based phar archives. Alternatively, a file extension may be specified with the second parameter.
For decompressing, the default file extensions are .phar and .phar.tar. Use this parameter to specify another file extension. Be aware that all executable phar archives must contain .phar in their filename.
A Phar object is returned.
Example #1 A Phar::decompress() example
$p = new Phar('/path/to/my.phar', 0, 'my.phar.gz');
$p['myfile.txt'] = 'hi';
$p['myfile2.txt'] = 'hi';
$p3 = $p2->decompress(); // creates /path/to/my.phar
