PharData::decompressFiles

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

PharData::decompressFiles — Decompresses all files in the current zip archive

설명

bool PharData::decompressFiles ( void )

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

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

For Zip-based archives, this method decompresses all files in the archive. The zlib or bzip2 extensions must be enabled to take advantage of this feature if any files are compressed using bzip2/zlib compression.

반환값

성공 시 TRUE를, 실패 시 FALSE를 반환합니다.

오류/예외

Throws BadMethodCallException if 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 PharData::decompressFiles() example


<?php
$p = new PharData('/path/to/my.zip');
$p['myfile.txt'] = 'hi';
$p['myfile2.txt'] = 'hi';
$p->compressFiles(Phar::GZ);
foreach ($p as $file) {
    var_dump($file->getFileName());
    var_dump($file->isCompressed());
    var_dump($file->isCompressed(Phar::BZ2));
    var_dump($file->isCompressed(Phar::GZ));
}
$p->decompressFiles();
foreach ($p as $file) {
    var_dump($file->getFileName());
    var_dump($file->isCompressed());
    var_dump($file->isCompressed(Phar::BZ2));
    var_dump($file->isCompressed(Phar::GZ));
}
?>
