RarEntry::getStream
(PECL rar >= 2.0.0)
RarEntry::getStream — Get file handler for entry
설명
public resource RarEntry::getStream
([ string $password
] )
The handler is not invalidated by calling
rar_close().
Warning
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.
인수
-
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().
반환값
The file handler 실패 시 FALSE를 반환합니다.
예제
Example #1 RarEntry::getStream() example
<?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 $buff;
else
break; //fread error
}
fclose($stream);
?>
