rar://
rar:// — RAR
Description
The wrapper takes the url encoded path to the RAR archive (relative or absolute),
an optional asterik (*), an optional number sign
(#) and an optional url encoded entry name, as stored in the
archive. Specifying an entry name requires the number sign; a leading forward
slash in the entry name is optional.
This wrapper can open both files and directories. When opening directories, the asterisk sign forces the directory entries names to be returned unencoded. If it's not specified, they will be returned url encoded – the reason for this is to allow the wrapper to be correctly used with built-in functionality like the RecursiveDirectoryIterator in the presence of file names that seem like url encoded data.
If the pound sign and the entry name part are not included, the root of the archive will be displayed. This differs from regular directories in that the resulting stream will not contain information such as the modification time, as the root directory is not stored in an individual entry in the archive. The usage of the wrapper with RecursiveDirectoryIterator requires the number sign to be included in the URL when accessing the root, so that the URLs of the children may be constructed correctly.
Note: This wrapper is not enabled by default
In order to use the rar:// wrapper, you must install the » rar extension available from » PECL.
rar:// Available since PECL rar 3.0.0
Usage
- rar://<url encoded archive name>[*][#[<url encoded entry name>]]
Examples
Example #1 Traversing a RAR archive
<?php
class MyRecDirIt extends RecursiveDirectoryIterator {
function current() {
return rawurldecode($this->getSubPathName()) .
(is_dir(parent::current())?" [DIR]":"");
}
}
$f = "rar://" . rawurlencode(dirname(__FILE__)) .
DIRECTORY_SEPARATOR . 'dirs_and_extra_headers.rar#';
$it = new RecursiveTreeIterator(new MyRecDirIt($f));
foreach ($it as $s) {
echo $s, "\n";
}
?>
The above example will output something similar to:
|-allow_everyone_ni [DIR]
|-file1.txt
|-file2_אּ.txt
|-with_streams.txt
\-אּ [DIR]
|-אּ\%2Fempty%2E [DIR]
| \-אּ\%2Fempty%2E\file7.txt
|-אּ\empty [DIR]
|-אּ\file3.txt
|-אּ\file4_אּ.txt
\-אּ\אּ_2 [DIR]
|-אּ\אּ_2\file5.txt
\-אּ\אּ_2\file6_אּ.txt
Example #2 Opening an encrypted file (header encryption)
<?php
$stream = fopen("rar://" .
rawurlencode(dirname(__FILE__)) . DIRECTORY_SEPARATOR .
'encrypted_headers.rar' . '#encfile1.txt', "r", false,
stream_context_create(
array(
'rar' =>
array(
'open_password' => 'samplepassword'
)
)
)
);
var_dump(stream_get_contents($stream));
/* creation and last access date is opt-in in WinRAR, hence most
* files don't have them */
var_dump(fstat($stream));
?>
The above example will output something similar to:
string(26) "Encrypted file 1 contents."
