我的代码有点工作,但我没有得到我想要的输出,我只是想要输出“Gentle Breeze”,而是我得到“SimpleXMLElement Object([0] => Gentle Breeze)”
这是我的代码:
<head>
<title>Open Weather API</title>
</head>
<body>
<?php
$url = "http://api.openweathermap.org/data/2.5/forecast/daily?q=London&mode=xml&units=metric&cnt=16&appid=Key";
$xml = simplexml_load_file($url);
foreach($xml->forecast->time as $times)
{
$windspeed[] = $times->windSpeed["name"];
}
print_r($windspeed[0])
?>
</body>
我尝试过使用echo而不是print_r,但输出的只是“Array”
以下是我从API中提取的XML示例:
<time day="2016-08-19">
<symbol number="500" name="light rain" var="10d"/>
<precipitation value="2.97" type="rain"/>
<windDirection deg="188" code="S" name="South"/>
<windSpeed mps="5.28" name="Gentle Breeze"/>
<temperature day="22.58" min="17.06" max="22.58" night="18.39" eve="18.61" morn="17.06"/>
<pressure unit="hPa" value="1012.32"/>
<humidity value="72" unit="%"/>
<clouds value="overcast clouds" all="92" unit="%"/>
</time>
我需要将它存储在一个数组中,以便我稍后可以在我的代码中调用它,我只是输出结果作为测试来查看存储在数组中的内容,我只是希望它存储“Gentle Breeze” “not”SimpleXMLElement Object([0] =&gt; Gentle Breeze)“
答案 0 :(得分:2)
简单的转换为字符串应该达到你想要的效果:
foreach($xml->forecast->time as $times)
{
$windspeed[] = (string) $times->windSpeed["name"];
}
答案 1 :(得分:-1)
尝试这样做:
$windspeed[] = $times->windSpeed->name;
或
var_dump ($times->windSpeed->name);
