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
?>Il precedente esempio visualizzerà qualcosa simile a:
bool(false)
