Phar::compress
(PHP >= 5.3.0, PECL phar >= 2.0.0)
Phar::compress — Compresses the entire Phar archive using Gzip or Bzip2 compression
Описание
public object Phar::compress ( int $compression [, string $extension ] )Замечание:
Для корректной работы с объектами Phar этому методу необходима установка значения php.ini phar.readonly в 0. В противном случае, будет выброшено исключение PharException.
For tar-based and phar-based phar archives, this method compresses the entire archive using gzip compression or bzip2 compression. The resulting file can be processed with the gunzip command/bunzip command, or accessed directly and transparently with the Phar extension.
For Zip-based phar archives, this method fails with an exception. The zlib extension must be enabled to compress with gzip compression, the bzip2 extension must be enabled in order to compress 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 renames the archive, appending .gz, .bz2 or removing the extension if passed Phar::NONE to remove compression. Alternatively, a file extension may be specified with the second parameter.
Список параметров
compression - Compression must be one of Phar::GZ, Phar::BZ2 to add compression, or Phar::NONE to remove compression.
extension - By default, the extension is .phar.gz or .phar.bz2 for compressing phar archives, and .phar.tar.gz or .phar.tar.bz2 for compressing tar archives. For decompressing, the default file extensions are .phar and .phar.tar.
Возвращаемые значения
Returns a Phar object.
Ошибки
Throws BadMethodCallException if the phar.readonly INI variable is on, the zlib extension is not available, or the bzip2 extension is not enabled.
Примеры
Пример #1 A Phar::compress() example
$p = new Phar('/path/to/my.phar', 0, 'my.phar');
$p['myfile.txt'] = 'hi';
$p['myfile2.txt'] = 'hi';
$p1 = $p->compress(Phar::GZ); // copies to /path/to/my.phar.gz
$p2 = $p->compress(Phar::BZ2); // copies to /path/to/my.phar.bz2
$p3 = $p2->compress(Phar::NONE); // exception: /path/to/my.phar already exists
