最后异常给出了错误php

Question

我正在尝试学习PHP,我刚刚转到Exceptions,当我尝试一个例子时

http://php.net/manual/en/language.exceptions.php

Example #2 Exception handling with a finally block

我得到一个错误

Parse error: syntax error, unexpected '{' in C:\xampp\htdocs\test\filename.php on line 13

<?php
function inverse($x) {
    if (!$x) {
        throw new Exception('Division by zero.');
    }
    else return 1/$x;
}

try {
    echo inverse(5) . "\n";
} catch (Exception $e) {
    echo 'Caught exception: ',  $e->getMessage(), "\n";
} finally {
    echo "First finally.\n";
}

try {
    echo inverse(0) . "\n";
} catch (Exception $e) {
    echo 'Caught exception: ',  $e->getMessage(), "\n";
} finally {
    echo "Second finally.\n";
}

// Continue execution
echo 'Hello World';

Answer 1

将finally在PHP 5.5中添加的try-catch块仍处于发展,它不为你工作的可能的原因是因为你使用PHP 5.4或更早版本.

您将无法使用finally,除非他们将其反向移植到早期的PHP版本或您使用的是5.5版本.
