走！AOP 框架使用帶有 include 語句的流過濾器來執(zhí)行代理生成。它在 PHP 7.3 中運(yùn)行良好，但現(xiàn)在在 PHP 7.4 beta 2 發(fā)布后，它看起來有些變化。不幸的是，流過濾器的文檔很差，所以我無法檢查發(fā)生了什么。也許有經(jīng)驗(yàn)的人會知道。檢查以下示例代碼：// index.phpinclude __DIR__ . '/SampleFilter.php';SampleFilter::register();$uri = 'php://filter/read=sample.filter/resource='. __DIR__ . '/Sample.php';$content = file_get_contents($uri);include $uri;Sample::printIt();// SampleFilter.phpclass SampleFilter extends php_user_filter{    public const PHP_FILTER_READ = 'php://filter/read=';    public const FILTER_IDENTIFIER = 'sample.filter';    protected $data = '';    protected static $filterId;    public static function register(string $filterId = self::FILTER_IDENTIFIER) : void    {        if (!empty(self::$filterId))         {            throw new RuntimeException('Stream filter already registered');        }        $result = stream_filter_register($filterId, __CLASS__);        if ($result === false)        {            throw new Exception('Stream filter was not registered');        }        self::$filterId = $filterId;    }    public static function getId() : string    {        if (empty(self::$filterId))        {            throw new Exception('Stream filter was not registered');        }        return self::$filterId;    }    public function filter($in, $out, &$consumed, $closing)    {        while ($bucket = stream_bucket_make_writeable($in))        {            $this->data .= $bucket->data;        }如您所見，$content 已正確修改代碼（完整）。但是在包含該文件時(shí)，它看起來像代碼被分割為原始文件長度。PHP 打印錯(cuò)誤：Parse error: syntax error, unexpected end of file in /(...)/Sample.php on line 9第 9 行是超出原始文件大小的地方。
