RarArchive::isBroken
rar_broken_is
(PECL rar >= 3.0.0)
RarArchive::isBroken -- rar_broken_is — 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:
This function determines whether an archive is incomplete, i.e., if a volume is missing or a volume is truncated.
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));
?>
