* ZipArchive: zip/unzip utility
|
||
|
|
*
|
||
|
|
* Zip usage example:
|
||
|
|
* ZipArchive zip(path, password, ZIP_CREATE|ZIP_TRUNCATE);
|
||
|
|
* zip.chdir("/src/dir");
|
||
|
|
* zip.add("file_or_directory");
|
||
|
|
* zip.add("…");
|
||
|
|
* zip.close();
|
||
|
|
*
|
||
|
|
* Unzip usage example:
|
||
|
|
* ZipArchive zip(path, password, ZIP_RDONLY);
|
||
|
|
* zip.chdir("/dst/dir");
|
||
|
|
* zip.extract("file_or_dir_prefix");
|
||
|
|
* zip.extract("…");
|
||
|
|
* zip.close();
|
||
|
|
*
|
||
|
|
* Encryption:
|
||
|
|
* - empty password ("") = no encryption (or set encmethod to ZIP_EM_NONE)
|
||
|
|
* - default encryption is AES 256 bit (supported by 7z for example)
