我正在尝试将从tmdbapi接收的嵌套json数据插入mysql数据库。
我已经知道如何插入嵌套的json了，但是由于我需要创建的新记录将具有多对多关系（电影和电影类型），因此我假设我必须插入多行具有不同电影类型的相同数据。
我一直在尝试使用另一个foreach循环的电影类型没有成功。我非常感谢你的帮助。

<?php

$api = "https://api.themoviedb.org/3/movie/popular?api_key=<<api-key>>&language=en-US&page=1";
$jsondata = file_get_contents($api);
//now you have result as associative array
$data = json_decode($jsondata, true);
$array_data = $data['results'];
$array_genre= $data['results']['genre'];//

include "indexmoviedb.php";
$stmt=$db->prepare("INSERT INTO movie VALUES(:title,:poster_path,:backdrop_path,:rating,:overview,:genre)");

foreach($array_data as $row){
foreach ($array_genre as $genrerow) {// I'm assuming I have to do something like this

$stmt->bindParam(":title",$row['title'] );
$stmt->bindParam(":poster_path",$row['poster_path'] );
$stmt->bindParam(":backdrop_path",$row['backdrop_path'] );
$stmt->bindParam(":rating",$row['vote_average'] );
$stmt->bindParam(":overview",$row['overview'] );
$stmt->bindParam(":genre",$row['genres_ids'][] );// what goes in here?
$stmt->execute();
}
}

 ?>

这是我要插入的json文件

{
  "results": [{
    "id": 351286,
    "vote_average": 6.6,
    "title": "Jurassic World: Fallen Kingdom",
    "popularity": 228.669,
    "poster_path": "/c9XxwwhPHdaImA2f1WEfEsbhaFB.jpg",
    "genre_ids": [
      28,
      12,
      878
    ],
    "backdrop_path": "/gBmrsugfWpiXRh13Vo3j0WW55qD.jpg"
  }]
}
