RarException::setUsingExceptions

(PECL rar >= 2.0.0)

RarException::setUsingExceptionsActivate and deactivate error handling with exceptions

Description

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):

Parameters

using_exceptions

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

Return Values

No value is returned.

Examples

Example #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
?>

The above example will output something similar to:

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
