PHP Untar-gz without exec()?
提问by Hyman Wilsdon
How would I untar-gz a file in php without the use of exec('tar')or any other commands, using pure PHP?
如何在不使用exec('tar')或任何其他命令的情况下使用纯 PHP解压 php 中的文件？
My problem is as follows; I have a 26mb tar.gz file that needs to be uploaded onto my server and extracted. I have tried using net2ftp to extract it, but it doesn't support tar.gz uncompressing after upload.
我的问题如下；我有一个 26mb 的 tar.gz 文件需要上传到我的服务器并提取。我试过用net2ftp解压，但不支持tar.gz上传后解压。
I'm using a free web host, so they don't allow any exec()commands, and they don't allow access to a prompt. So how would I go about untaring this?
我使用的是免费的网络主机，所以他们不允许任何exec()命令，也不允许访问提示。那么我将如何解开这个呢？

Since PHP 5.3.0 you do not need to use Archive_Tar.
从 PHP 5.3.0 开始，您不需要使用Archive_Tar.
There is new class to work on tar archive: The PharData class.
有一个新的类可以处理 tar 存档：PharData 类。
To extract an archive (using PharData::extractTo()which work like the ZipArchive::extractTo()):
要提取存档（使用PharData::extractTo()类似于 的工作方式ZipArchive::extractTo()）：
try {
$phar = new PharData('myphar.tar');
$phar->extractTo('/full/path'); // extract all files
} catch (Exception $e) {
// handle errors
}
And if you have a tar.gz archive, just decompress it before extract (using PharData::decompress()):
如果您有 tar.gz 存档，只需在提取前解压缩（使用PharData::decompress()）：
// decompress from gz
$p = new PharData('/path/to/my.tar.gz');
$p->decompress(); // creates /path/to/my.tar
// unarchive from the tar
$phar = new PharData('/path/to/my.tar');
$phar->extractTo('/full/path');

PEAR provides the Archive_Tarclass, which supports both Gzip and BZ2 compressions, provided you have the zlib and bz2 extensions loaded, respectively.
PEAR 提供了Archive_Tar类，它支持 Gzip 和 BZ2 压缩，前提是您分别加载了 zlib 和 bz2 扩展。
