RarException::setUsingExceptions

(PECL rar >= 2.0.0)

RarException::setUsingExceptions — Activate and deactivate error handling with exceptions

说明

public static RarException::setUsingExceptions(bool $using_exceptions): void

If and only if the argument is true, then, instead of emitting warnings and returning a special value indicating error when the UnRAR library encounters an error, an exception of type RarException will be thrown.

Exceptions will also be thrown for the following errors, which occur outside the library (their error code will be -1):

attempting some operations on a closed RarArchive object or a RarEntry object relative to the first;
attempting to get an entry that does not exist with RarArchive::getEntry().

参数

using_exceptions: Should be true to activate exception throwing, false to deactivate (the default).

返回值

没有返回值。

范例

示例 #1 RarException::setUsingExceptions() example


<?php
var_dump(RarException::isUsingExceptions());
$arch = RarArchive::open("does_not_exist.rar");
var_dump($arch);

RarException::setUsingExceptions(true);
var_dump(RarException::isUsingExceptions());
$arch = RarArchive::open("does_not_exist.rar");
var_dump($arch); //not reached
?>

以上例程的输出类似于：

bool(false)

Warning: RarArchive::open(): Failed to open does_not_exist.rar: ERAR_EOPEN (file open error) in C:\php_rar\trunk\tests\test.php on line 3
bool(false)
bool(true)

Fatal error: Uncaught exception 'RarException' with message 'unRAR internal error: Failed to open does_not_exist.rar: ERAR_EOPEN (file open error)' in C:\php_rar\trunk\tests\test.php:8
Stack trace:
#0 C:\php_rar\trunk\tests\test.php(8): RarArchive::open('does_not_exist....')
