我正在尝试使用此类通过URL获取IMDB，该类打算从URL EX获取IMDB信息：http://www.imdb.com/title/tt0371746/
相反，它会返回错误：{ $param['error'] = "No Title found in Search Results!"; return $param; }
我在网址上没有电影时会产生错误，为什么每次都会返回错误？即使我在每个网址上都有一部电影我添加了吗？！
这是班级：

这背后有一些错误：
IMDBGrabber::scruburl($input)方法中有正确的正则表达式，双引号之后和http之前可能有字符。如果我

它。使用当前的方法，您将在几次之后被禁止
数十万次尝试。所以固定的正则表达式是： $urls = $this->match_all('/<a[\s\S]*?href="[\s\S]*?(http[s]{0,1}:\/\/www.imdb.com\/title\/[\s\S]*?)\//', $content, 1);
stripos($content, "<meta

That ride ends badly when Stark's Humvee that he's riding in is attacked by enemy combatants. He survives - barely - with a chest full of shrapnel and a car battery attached to his heart. In order to survive he comes up with a way to miniaturize the battery and figures out that the battery can power something else. Thus Iron Man is born.

带有一堆PHP通知。
但这一切都是维持的噩梦，我不得不说，代码并不是最好的。考虑使用this方法或基于XML / xpath寻址的解析器。另见this。
