# Phar::compressAllFilesBZIP2

(PHP >= 5.3.0, PECL phar >= 1.0.0)

Phar::compressAllFilesBZIP2 — Compresses all files in the current Phar archive using Bzip2 compression

### 설명

bool Phar::compressAllFilesBZIP2 ( void )

> Note: 이 메쏘드는 phar 확장 2.0.0부터 제거되었습니다. 대신, Phar::compress(), Phar::decompress(), Phar::compressFiles(), Phar::decompressFiles()를 사용할 수 있습니다.

> Note: 이 메쏘드가 Phar 객체에 작용하려면 php.ini 설정 phar.readonly을 0으로 설정해야 합니다. 그렇지 않으면, PharException이 발생합니다.

This method compresses all files in the Phar archive using bzip2 compression. The bzip2 extension must be enabled to take advantage of this feature. In addition, if any files are already compressed using gzip compression, the zlib extension must be enabled in order to decompress the files prior to re-compressing 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.

### 반환값

성공할 경우 `TRUE`를, 실패할 경우 `FALSE`를 반환합니다.

### 오류/예외

Throws BadMethodCallException if the phar.readonly INI variable is on, the bzip2 extension is not available, or if any files are compressed using gzip compression and the zlib extension is not enabled.

### 예제

Example #1 A Phar::compressAllFilesBZIP2() example

`<?php
$p = new Phar('/path/to/my.phar', 0, 'my.phar');
$p['myfile.txt'] = 'hi';
$p['myfile2.txt'] = 'hi';
foreach ($p as $file) {
var_dump($file->getFileName());
var_dump($file->isCompressed());
var_dump($file->isCompressedBZIP2());
var_dump($file->isCompressedGZ());
}
$p->compressAllFilesBZIP2();
foreach ($p as $file) {
var_dump($file->getFileName());
var_dump($file->isCompressed());
var_dump($file->isCompressedBZIP2());
var_dump($file->isCompressedGZ());
}
?>`

위 예제의 출력:

    string(10) "myfile.txt"
    bool(false)
    bool(false)
    bool(false)
    string(11) "myfile2.txt"
    bool(false)
    bool(false)
    bool(false)
    string(10) "myfile.txt"
    bool(true)
    bool(true)
    bool(false)
    string(11) "myfile2.txt"
    bool(true)
    bool(true)
    bool(false)

### 참고

- PharFileInfo::getCompressedSize() - Returns the actual size of the file (with compression) inside the Phar archive
- PharFileInfo::isCompressedBZIP2() - Returns whether the entry is compressed using bzip2
- PharFileInfo::isCompressed() - Returns whether the entry is compressed
- PharFileInfo::isCompressedGZ() - Returns whether the entry is compressed using gz
- PharFileInfo::setCompressedBZIP2() - Compresses the current Phar entry within the phar using Bzip2 compression
- PharFileInfo::setUncompressed() - Uncompresses the current Phar entry within the phar, if it is compressed
- PharFileInfo::setCompressedGZ() - Compresses the current Phar entry within the phar using gz compression
- Phar::canCompress() - Returns whether phar extension supports compression using either zlib or bzip2
- Phar::isCompressed() - Returns Phar::GZ or PHAR::BZ2 if the entire phar archive is compressed (.tar.gz/tar.bz and so on)
- Phar::compressAllFilesGZ() - Compresses all files in the current Phar archive using Gzip compression
- Phar::getSupportedCompression() - Return array of supported compression algorithms
- Phar::uncompressAllFiles() - Uncompresses all files in the current Phar archive
