php中的json解析响应

我的所有JSON数据都将为NULL 这是我的密码

$jsons1 = file_get_contents($api_url); // returns JSON
        $jsons=json_decode($jsons1);

        foreach ($jsons as $json)
        {
        echo "\n";
        echo "<ul>";
        echo "<li>";
        echo "\nTitle : ".$json->title."\n";
        echo "\nContent: ".$json->content."\n";
        echo "</li>";
        echo "</ul>";
        }

请在这方面提供帮助

下面是

$jsons1

变量的输出

{"results":[{"title": "Temp, Russia - Wikipedia, the free encyclopedia","kwic": "Coordinates : 52°03′N 39°44′E  /  52.05°N 39.733°E  / 52.05; 39.733  tenmp ( Russian : УÑмань ) is a town and the administrative center of ...","content": "","url": "http://en.wikipedia.org/wiki/sdfds,_Russia","iurl": "","domain": "en.wikipedia.org","author": "","news": false,"votes": "1","date": 1357744155518,"related":[]}],"query": "tenp","suggestions":[],"count":96,"start":1,"length":10,"time": "412"}

您有包含数据的对象结果

因此，您只需修复Foreach语句即可..>

    foreach ($jsons->results as $json) { ... }

尝试

$j='{“结果”：[{“标题”：“Temp，俄罗斯-维基百科，免费百科全书”，“kwic”：“坐标：52°03–N39”“44–Eï/52.05”“N39.733”“Eï/52.05”；39.733 tenmp（俄语：39.733TENMP）是一座城镇，是……的行政中心，”，“内容”：“url”："http://en.wikipedia.org/wiki/sdfds，_Russia，，_Russia，，“iurl:”，“domain:“en.wikipedia.org”，“author:”，“news:“false”，“Devots:“1”，“date”：1357744155518，“related:[]}]，“query:“tenp”，“suggestions:”，“count:“96”，“start:”1，“length:“10”，“time:“412”}；
$data=json_decode（$j，true）；
foreach（$data[“results”]作为$key=>$val）{
回音“\n”；
回声“
”；
回声“
”；
回显“\n标题：.$val[“标题”]。\n”；
回显“\n内容：.$val[“内容”]。\n”；
回声“
”；
回声“
”；
}

现在，results元素中只有一个数据，因此如果有更多的数据，循环会更好。

将json字符串发布到你的问题中。另外，

打印你的
$jsons
变量，看看你是否得到了你认为得到的数组。@AbhikChakraborty发布..@Kryten我得到了响应，我相信是json_decode将起作用，将解码的对象称为
$jsons
或
$json
是很蹩脚的。任何名为json的东西都应该是json字符串。所有解码的东西都是对象。
    foreach ($jsons->results as $json) { ... }

$j = '{"results":[{"title": "Temp, Russia - Wikipedia, the free encyclopedia","kwic": "Coordinates : 52°03′N 39°44′E  /  52.05°N 39.733°E  / 52.05; 39.733  tenmp ( Russian : УÑмань ) is a town and the administrative center of ...","content": "","url": "http://en.wikipedia.org/wiki/sdfds,_Russia","iurl": "","domain": "en.wikipedia.org","author": "","news": false,"votes": "1","date": 1357744155518,"related":[]}],"query": "tenp","suggestions":[],"count":96,"start":1,"length":10,"time": "412"}';

$data = json_decode($j,true);

foreach ($data["results"] as $key=>$val){
    echo "\n";
    echo "<ul>";
    echo "<li>";
    echo "\nTitle : ".$val["title"]."\n";
    echo "\nContent: ".$val["content"]."\n";
    echo "</li>";
    echo "</ul>";
}
