Question

所以我正在尝试创建一个jquery / ajax自动完成表单，它使用last.fm api自动完成歌曲的标题，无论用户输入什么，我遇到的问题是我似乎无法获得最后一个fm数据以适当的json格式返回。这是我的jquery插件（link to autocomplete）要返回的格式：

{
    "suggestions": [
        { "value": "United Arab Emirates", "data": "AE" },
        { "value": "United Kingdom",       "data": "UK" },
        { "value": "United States",        "data": "US" }
    ]
}

这里基本上是我在我的php脚本中执行的操作将json返回到自动完成插件：

                $titleName = "what's my age";
                $limit = 1;
                $results = Track::search($titleName, $limit);
                print_array($results);
                echo "<ul>";
                while ($title = $results->current()) {
                    echo $limit;
                    echo "<li><div>";
                    echo "Artist: " . $title->getArtist() . "<br>";
                    echo "Album: " . $title->getAlbum() . "<br>";
                    echo "Duration: " . $title->getDuration() . "<br>";
                    echo "getWiki: " . $title->getWiki() . "<br>";
                    echo "name: " . $title->getName() . "<br>";
                    echo "</div></li>";
                    $jsonArray['suggestions'] = array('Name'.$limit => $title->getName(), 'Artist'.$limit => $title->getArtist());
                    $limit++;
                    $title = $results->next();
                }
                echo "</ul>";
                print_array($jsonArray);
                echo json_encode($jsonArray);

echo和print语句仅用于测试，但这是json_encode返回的内容：

{"suggestions":{"Name2":"Blink vs. Jay-Z - what's my age again","Artist2":"Dj Tech1"}}

这就是返回的内容（通过回声测试）：

1
Artist: Blink 1-82
Album: 
Duration: 0
getWiki: 
name: What's My Age Again?
2
Artist: Dj Tech1
Album: 
Duration: 0
getWiki: 
name: Blink vs. Jay-Z - what's my age again

所以我知道代码工作正常所以是sdk自动完成等等。我也明白，每次循环时都会删除while循环中的数组，而我还没有解决这个问题，但是那个问题除此之外，json没有以请求的格式返回，我似乎无法找到构建数组的正确方法，以便以正确的格式，任何想法得到它？

Answer 1

$suggestionsArr['suggestions'] = [];

foreach (range(1,3) as $key => $value) {
    array_push($suggestionsArr['suggestions'], ['name' => 'Song1', 'artist' => 'Artist1']);
}

echo json_encode($suggestionsArr);

从lastfm api返回json
