RarEntry::getStream

(PECL rar >= 2.0.0)

RarEntry::getStream — Get file handler for entry

Beschreibung

public RarEntry::getStream ([ string $password ] ) : resource

Returns a file handler that supports read operations. This handler provides on-the-fly decompression for this entry.

The handler is not invalidated by calling rar_close().

Warnung

The resulting stream has no integrity verification. In particular, file corruption and decryption with a wrong a key will not be detected. It is the programmer's responsability to use the entry's CRC to check for integrity, if he so wishes.

Parameter-Liste

password

The password used to encrypt this entry. If the entry is not encrypted, this value will not be used and can be omitted. If this parameter is omitted and the entry is encrypted, the password given to rar_open(), if any, will be used. If a wrong password is given, either explicitly or implicitly via rar_open(), this method's resulting stream will produce wrong output. If no password is given and one is required, this method will fail and return FALSE. You can check whether an entry is encrypted with RarEntry::isEncrypted().

Rückgabewerte

The file handler Im Fehlerfall wird FALSE zurückgegeben..

Changelog

Version Beschreibung
3.0.0 Support for RAR archives with repeated entry names is no longer defective.

<?php

$rar_file = rar_open('example.rar');
if ($rar_file === false)
    die("Failed to open Rar archive");

$entry = rar_entry_get($rar_file, 'Dir/file.txt');
if ($entry === false)
    die("Failed to find such entry");

$stream = $entry->getStream();
if ($stream === false)
    die("Failed to obtain stream.");

rar_close($rar_file); //stream is independent from file

while (!feof($stream)) {
    $buff = fread($stream, 8192);
    if ($buff !== false)
        echo $buff;
    else
        break; //fread error
}
