RarArchive::isBroken()
(PECL rar >= 3.0.0)
Test whether an archive is broken(incomplete)
说明
面向对象风格(method):
public RarArchive::isBroken(void): bool
过程化风格:
rar_broken_is(RarArchive$rarfile): bool
This function determines whether an archive is incomplete, i.e., if a volume is missing or a volume is truncated.
参数
- $rarfile
A RarArchive object, opened with rar_open().
返回值
Returns TRUE if the archive is broken,FALSE otherwise. This function may also return FALSE if the passed file has already been closed. The only way to tell the two cases apart is to enable exceptions with RarException::setUsingExceptions(); however, this should be unnecessary as a program should not operate on closed files.
范例
Example #1 面向对象风格
<?php
function retnull() { return null; }
$file = dirname(__FILE__) . "/multi_broken.part1.rar";
/* Third argument is used to omit notice */
$arch = RarArchive::open($file, null, 'retnull');
var_dump($arch->isBroken());
?>
以上例程的输出类似于：
bool(true)
Example #2 过程化风格
<?php
function retnull() { return null; }
$file = dirname(__FILE__) . "/multi_broken.part1.rar";
/* Third argument is used to omit notice */
$arch = rar_open($file, null, 'retnull');
var_dump(rar_broken_is($arch));
?>
