PharData::decompressFiles

(PHP 5 >= 5.3.0, PHP 7, PECL phar >= 2.0.0)

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

说明

PharData::decompressFiles ( ) : bool

Note:

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.

返回值

成功时返回 true， 或者在失败时返回 false。

错误／异常

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.

范例

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));}?>

以上例程会输出：

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)
