我正在尝试运行这个例子＃1，来自这个页面：http://php.net/manual/en/language.exceptions.php

<?php
function inverse($x) {
    if (!$x) {
        throw new Exception('Division by zero.');
    }
    return 1/$x;
}
try {
    echo inverse(5) . "n";
    echo inverse(0) . "n";
} catch (Exception $e) {
    echo 'Caught exception: ',  $e->getMessage(), "n";
}
// Continue execution
echo "Hello Worldn";
?>

然而，我得到的输出不是预期的：

0.2
Fatal error: Uncaught exception 'Exception' with message 'Division by zero.' 
in xxx:
7 Stack trace: #0 xxx(14): inverse(0) #1 {main} thrown in xxx on line 7

我使用的开发环境是UniServer 3.5和PHP 5.2.3
