嵌套数组中的PHP foreach循环

我正在尝试为我的项目使用非官方的IMDb api.我用了这段代码.

<form name="search-imdb" autocomplete="off" method="post" action="<?PHP echo $_SERVER['PHP_SELF']; ?>">
<input type="text" name="q" title="Type Name, Title, Character etc and hit Enter" placeholder="Type Name, Title, Character etc and hit Enter" size="50" />
<input type="submit" name="submit" title="Click to Fetch Data from IMDb" value="Search IMDb" />
</form>

<?PHP

if (isset($_POST['submit'])){
    $user_search = $_POST['q'];
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, "imdb.wemakesites.net/api/search?q=".$user_search); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $output = curl_exec($ch);
    $array = json_decode($output, true);
    print_r($array);

   foreach ($array as $key => $data){
    if(is_array($data)){
        foreach($data as $subkey => $results){
            if(is_array($results)){
                foreach($results as $key => $titles){
                    echo $titles."<br />";
                }
            } else {
                echo $results."<br />";
            }
        }
    } else {
        echo $data."<br />";
    }
}
    curl_close($ch);
} else {

}
?>

我只需要获取“titles”数组的值. (title,id,url)这是JSON代码.

Array{
"status": "success",
"code": 200,
"message": "ok",
"term": "jQuery21409989625962002346_1459839763205&q",
"search_url":"http://www.imdb.com/find?q=batmansuperman&s=all5703b359add1b",
"data": {
    "results": {
        "titles": [
            {
                "title": "Batman",
                "id": "tt0096895",
                "url":"http://www.imdb.com/title/tt0096895/"
            },
            {
                "title": "Batman",
                "id": "tt0059968",
                "url":"http://www.imdb.com/title/tt0059968/"
            },
            {
                "title" :"Batman v Superman: Dawn of Justice",
                "id": "tt2975590",
                "url":"http://www.imdb.com/title/tt2975590/"
            },
            {
                "title": "Batman Begins",
                "id": "tt0372784",
                "url":"http://www.imdb.com/title/tt0372784/
            }
        ]
    }
}

这是我在JSON解码后的$数组.

谁能告诉我这里我做错了什么？我收到此错误 – “数组到字符串转换”

我已经尝试解决了几个小时,我一直在寻找互联网上的答案.一些帮助将非常感谢.谢谢.

解决方法:

从我看到的,这看起来像一个json而不是一个数组.在这种情况下,您应该首先执行此操作：

$array =  json_decode($array, true);

当涉及到数组遍历时,你可以尝试这样的事情：

foreach($array['data']['results']['titles'] as $data) {
    echo "Title:".$data['title'];
    echo "<br/>";
    echo "ID:".$data['id'];
    echo "<br/>";
    echo "URL:".$data['url'];
    echo "<hr/>";
}

希望这可以帮助.
