PHP 5.6.0 released

RarArchive::open

rar_open

(PECL rar >= 2.0.0)

RarArchive::open -- rar_openOpen RAR archive

Descrição

Estilo orientado à objeto (method):

public static RarArchive RarArchive::open ( string $filename [, string $password = NULL [, callable $volume_callback = NULL ]] )

Estilo procedural:

RarArchive rar_open ( string $filename [, string $password = NULL [, callable $volume_callback = NULL ]] )

Open specified RAR archive and return RarArchive instance representing it.

Nota:

If opening a multi-volume archive, the path of the first volume should be passed as the first parameter. Otherwise, not all files will be shown. This is by design.

Parâmetros

filename

Path to the Rar archive.

password

A plain password, if needed to decrypt the headers. It will also be used by default if encrypted files are found. Note that the files may have different passwords in respect to the headers and among them.

volume_callback

A function that receives one parameter – the path of the volume that was not found – and returns a string with the correct path for such volume or NULL if such volume does not exist or is not known. The programmer should ensure the passed function doesn't cause loops as this function is called repeatedly if the path returned in a previous call did not correspond to the needed volume. Specifying this parameter omits the notice that would otherwise be emitted whenever a volume is not found; an implementation that only returns NULL can therefore be used to merely omit such notices.

Aviso

Prior to version 2.0.0, this function would not handle relative paths correctly. Use realpath() as a workaround.

Valor Retornado

Returns the requested RarArchive instance ou FALSE em caso de falha.

Changelog

Versão Descrição
3.0.0 volume_callback was added.

Exemplos

Exemplo #1 Estilo orientado à objeto

<?php
$rar_arch 
RarArchive::open('encrypted_headers.rar''samplepassword');
if (
$rar_arch === FALSE)
    die(
"Failed opening file");
    
$entries $rar_arch->getEntries();
if (
$entries === FALSE)
    die(
"Failed fetching entries");

echo 
"Found " count($entries) . " files.\n";

if (empty(
$entries))
    die(
"No valid entries found.");
    
$stream reset($entries)->getStream();
if (
$stream === FALSE)
    die(
"Failed opening first file");

$rar_arch->close();

echo 
"Content of first one follows:\n";
echo 
stream_get_contents($stream);

fclose($stream);
?>

O exemplo acima irá imprimir algo similar à:

Found 2 files.
Content of first one follows:
Encrypted file 1 contents.

Exemplo #2 Estilo procedural

<?php
$rar_arch 
rar_open('encrypted_headers.rar''samplepassword');
if (
$rar_arch === FALSE)
    die(
"Failed opening file");
    
$entries rar_list($rar_arch);
if (
$entries === FALSE)
    die(
"Failed fetching entries");

echo 
"Found " count($entries) . " files.\n";

if (empty(
$entries))
    die(
"No valid entries found.");
    
$stream reset($entries)->getStream();
if (
$stream === FALSE)
    die(
"Failed opening first file");

rar_close($rar_arch);

echo 
"Content of first one follows:\n";
echo 
stream_get_contents($stream);

fclose($stream);
?>

Exemplo #3 Volume Callback

<?php
/* In this example, there's a volume named multi_broken.part1.rar
 * whose next volume is named multi.part2.rar */
function resolve($vol) {
    if (
preg_match('/_broken/'$vol))
        return 
str_replace('_broken'''$vol);
    else
        return 
null;
}
$rar_file1 rar_open(dirname(__FILE__).'/multi_broken.part1.rar'null'resolve');
$entry $rar_file1->getEntry('file2.txt');
$entry->extract(nulldirname(__FILE__) . "/temp_file2.txt");
?>
