以上是我从Zillow Api获得的回复，我从回复中获取了值，如下所示：

zpid => 48897608
links:
homedetails => http://www.zillow.com/homedetails/13546-36th-Ave-NE-Seattle-WA-98125/48897608_zpid/
graphsanddata => http://www.zillow.com/homedetails/13546-36th-Ave-NE-Seattle-WA-98125/48897608_zpid/#charts-and-data
mapthishome => http://www.zillow.com/homes/48897608_zpid/
comparables => http://www.zillow.com/homes/comps/48897608_zpid/
address:
street => 13546 36th Ave NE
zipcode => 98125
city => Seattle
state => WA
latitude => 47.727631
longitude => -122.289193
zestimate:
amount => 393735
last-updated => 03/12/2017

我使用下面的代码获得了这个：

$jsonIterator = new RecursiveIteratorIterator(
    new RecursiveArrayIterator(json_decode($json, TRUE)),
    RecursiveIteratorIterator::SELF_FIRST);

foreach ($jsonIterator as $key => $val) {
    if(is_array($val)) {
        echo "$key:\n";
    } else {
        echo "$key => $val\n";
    }
}

现在我的问题是如何获得单个值，如下面的格式？

<li>zipid:48897608</li>
<li>low:374048</li>

<li>last-updated:03/12/2017</li>

Answer 1

这是因为列表标签在页面上被处理为html标签。换句话说，它不是作为纯文本处理的。在这种情况下，我们应该替换＆＃39;＆lt;＆＃39;和＆＃39;＆gt;＆＃39;用＆＃39;＆amp; lt＆＃39;和＆＃39;＆amp; gt＆＃39;。

这是代码行。

foreach ($arr as $key=>$val) {
    echo "&ltli&gt{$key}:{$val}&lt/li&gt";
    echo '<br>';
}

希望它对你有所帮助。

谢谢！

Answer 2

我认为答案就在您的问题中，只需修改您的if条件：

echo '<ul>';
foreach ($jsonIterator as $key => $val) {
    if(!is_array($val)) {
        echo '<li>'.$key.':'.$val.'</li>';
    } 
}
echo '</ul>';

使用PHP从url响应json响应
