使用不同的文件名将文件添加到 PHP 中的 Tar 存档 [英] Adding files to a Tar Archive in PHP with different filenames

问题描述

我目前正在使用 Archive-Tar Pear 扩展用于 PHP 将文件集合添加到 Tar 存档中.

I'm currently using the Archive-Tar Pear extension for PHP to add a collection of files into a Tar Archive.

这些文件存储在带有额外扩展名的文件管理器中例如

These files are stored on a filer with an extra extension e.g.

 filename.tgz.104850209.t or filename2.doc.2154395.t

我想在添加文件时删除这个额外的扩展名，以便我的 Tar Archive 包含以下文件:filename.tgz 和 filename2.doc

I'd like to remove this extra extension while adding the files so that my Tar Archive would have the files: filename.tgz and filename2.doc

有没有办法在添加到存档之前不必先复制/重命名源文件?

Is there a way of doing that without having to copy/rename the source files first before adding to the Archive?

谢谢，标记.

推荐答案

Archive_Tar 的最新版本尚不支持这种开箱即用的功能.部分功能在 _addFile() 中，另一部分在 _addString() 中.

Archive_Tar in its latest version does not yet support such a functionality out of the box. Part of the functionality is in _addFile() and the other part in _addString().

最简单的方法可能是从 Archive_Tar 扩展并将所有调用代理到 ​​_writeHeaderBlock() 这是公共的，在文件名参数上应用映射，以便在写入标题时重命名它.

Most easy is probably to extend from Archive_Tar and proxy all calls to _writeHeaderBlock() which is public, applying a map on the filename parameter so to rename it when written into headers.

class Patched_Archive_Tar extends Archive_Tar
{
    var $renameMap = array();

    function _writeHeaderBlock($p_filename, $p_size, $p_mtime=0, $p_perms=0,
                               $p_type='', $p_uid=0, $p_gid=0)
    {
        return parent::_writeHeaderBlock($this->_translateFilename($p_filename), 
                                  $p_size, $p_mtime=0, $p_perms=0,
                                  $p_type='', $p_uid=0, $p_gid=0);
    }

    function _translateFilename($orignal)
    {
        $map = $this->renameMap;
        if (isset($map[$orignal])) {
            return $map[$orignal];
        }

        return $original;
    }
}

用法:

$obj = new Patched_Archive_Tar('dummy.tar'); // name of archive

$files = array('mystuff/ad.gif', 
               'mystuff/alcon.doc.t', 
               'mystuff/alcon.xls.t');   // files to store in archive

$obj->renameMap = array(
    'mystuff/alcon.doc.t' => 'mystuff/alcon.doc',
    'mystuff/alcon.xls.t' => 'mystuff/alcon.xls',
)  // files to rename

if ($obj->create($files)) {
    echo 'Created successfully!';
} else {
    echo 'Error in file creation';
}

这又快又脏，但希望有用.为了更好地查看我在开头注意到的函数 _addFile() 和 _addString()，您基本上想要另一个能够添加文件的函数(与 _addFile()) 通过指定文件名(与 _addString() 一样).

This is quick and dirty but hopefully worky. For something better see the function I noticed at the beginning _addFile() and _addString(), you basically want another one that is able to add a file (as with _addFile()) by specifiying the filename (as with _addString()).
