function doSomething() {
    $resource = createResource();
    try {
        $result = useResource($resource);
    } catch (Exception $e) {
        releaseResource($resource);
        log($e->getMessage());
        exit();
    }
    releaseResource($resource);
    return $result;

//使用finally后
function doSomething2() {
    $resource = createResource();
    try {
        $result = useResource($resource);
        return $result;
    } catch (Exception $e) {
