Phar::compressFiles

(PHP >= 5.3.0, PECL phar >= 2.0.0)

Phar::compressFiles — Compresses all files in the current Phar archive

설명

public void Phar::compressFiles ( int $compression )

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

For tar-based phar archives, this method throws a BadMethodCallException, as compression of individual files within a tar archive is not supported by the file format. Use Phar::compress() to compress an entire tar-based phar archive.

For Zip-based and phar-based phar archives, this method compresses all files in the Phar archive using the specified compression. The zlib or bzip2 extensions must be enabled to take advantage of this feature. In addition, if any files are already compressed using bzip2/zlib compression, the respective extension must be enabled in order to decompress the files prior to re-compressing. As with all functionality that modifies the contents of a phar, the phar.readonly INI variable must be off in order to succeed.

인수

compression: Compression must be one of Phar::GZ, Phar::BZ2 to add compression, or Phar::NONE to remove compression.

반환값

값을 반환하지 않습니다.

오류/예외

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

예제

Example #1 A Phar::compressFiles() 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->isCompressed(Phar::BZ2));
    var_dump($file->isCompressed(Phar::GZ));
}
$p->compressFiles(Phar::GZ);
foreach ($p as $file) {
    var_dump($file->getFileName());
    var_dump($file->isCompressed());
    var_dump($file->isCompressed(Phar::BZ2));
    var_dump($file->isCompressed(Phar::GZ));
}
?>

참고

PharFileInfo::getCompressedSize() - Returns the actual size of the file (with compression) inside the Phar archive
PharFileInfo::isCompressed() - Returns whether the entry is compressed
PharFileInfo::compress() - Compresses the current Phar entry with either zlib or bzip2 compression
PharFileInfo::decompress() - Decompresses the current Phar entry within the phar
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::decompressFiles() - Decompresses all files in the current Phar archive
Phar::getSupportedCompression() - Return array of supported compression algorithms
Phar::compress() - Compresses the entire Phar archive using Gzip or Bzip2 compression
Phar::decompress() - Decompresses the entire Phar archive

Compressing the entire archive

$phar->compress();

overrides your stub file.



Use compressFiles to have the the files compressed keeping your own stub in tact (which is not being compressed).

The compression is a little bit worth (since one file is left uncompressed), but enables you to have your own stub file executed with browser requests.



Don't get confused, compressing doesn't rise the security level of your code or obfuscating it strongly enough. The source code of your compressed phar is still easy to read.
