PharData::decompressFiles — Decompresses all files in the current zip archive
注意:
此方法需要 将 php.ini 中的
phar.readonly设为0以适合 Phar 对象. 否则, 将抛出PharException.
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.
此函数没有参数。
总是返回 true。
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.
示例 #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));
}
?>以上示例会输出：
string(10) "myfile.txt" int(4096) bool(false) bool(true) string(11) "myfile2.txt" int(4096) bool(false) bool(true) string(10) "myfile.txt" bool(false) bool(false) bool(false) string(11) "myfile2.txt" bool(false) bool(false) bool(false)
