Most of the good jokes were shown in the trailers, so if you\u0027ve seen the trailer then it\u0027s probably not worth the money. There were 3 of us watched this and although we all loved the despicable movies none of us enjoyed this. My son (11) said it felt like it was 2 hours long it was so boring. I can\u0027t really explain why it came across as so poor - but it just seemed really lazy and without Gru to play against the Minnions were just to simple. It was slapstick with no soul. The music although quite good didn\u0027t really seem to fit the film - just seemed to be tacked on at bit were they felt they should have a soundtrack and a famous song. Buy yourself a copy of despicable me and watch it again and again. Much better value for money! This just felt rushed, with loads of stock jokes, maybe hoping enough of them would hit the mark - they didn\u0027t.",

我想从这段php代码中得到1.genre、2.director、3.dateCreated、4.duration、5.uploadDate from JSON（application/ld+JSON），我如何做到这一点？一些帮助谢谢您。您将JSON数据转换为HTML页面。 所以你必须 1） 仅检索JSON数据 2） 解析JSON并对其进行处理
$id = 'tt0159365' ; // example id
$c = file_get_contents("https://www.imdb.com/title/$id");
// retrieve the JSON data
$d = new DomDocument();
@$d->loadHTML($c);
// parse the HTML to retrieve the "ld+json" only
$xp = new domxpath($d);
$jsonScripts = $xp->query( '//script[@type="application/ld+json"]' );
$json = trim( $jsonScripts->item(0)->nodeValue ); // get the first script only (it should be unique anyway)
// decode the JSON string we find into a associative array
$data = json_decode( $json, true );
// you can now use this array to query the data you want
$duration = $data['duration'];
echo "Duration: $duration" ;
$director = $data['director']['name'] ;
echo "Director : $director" ;

您是要在客户端获取JS/jQuery中的值，还是在服务器端获取PHP代码？如果是后者，“javascript”和“jquery”标记似乎不相关，我试图从
application/ld+json“duration”：“PT1H31M”application/ld+jsonforeach（$xp->query（//script[@type='application/ld+json']）作为$du{$duration=$du->getAttribute（“duration”）；“duration”：“PT1H31M”application/ld+jsonapplication/ld+jsonforeach（$xp->query（//脚本[@type='application/ld+json']”作为$du）{$duration=$du->getAttribute（“duration”）durationdirector，dateCreated and genredateCreated$data['review'[/dateCreated']打印（$data）durationdateCreated and genre主管dateCreated$data['review']['dateCreated']打印（$data）；
