我正在嘗試在網(wǎng)站上顯示以下數(shù)據(jù)：-"daily":[{"dt":1593864000,"sunrise":1593834201,"sunset":1593894929,"temp":{"day":18.47,"min":17.83,"max":18.71,"night":17.83,"eve":18.71,"morn":18.47},"feels_like":{"day":16,"night":13.09,"eve":16.54,"morn":16},"pressure":1006,"humidity":77,"dew_point":14.37,"wind_speed":5.51,"wind_deg":244,"weather":[{"id":500,"main":"Rain","description":"light rain","icon":"10d"}],"clouds":90,"uvi":7.08}我提取除天氣部分中的條目之外的任何條目，因?yàn)槲沂褂玫拇a認(rèn)為天氣數(shù)據(jù)是一個(gè)單獨(dú)的數(shù)組。與顯示數(shù)據(jù)相關(guān)的代碼部分是：-<span class="min-temperature"> Minimum Temperature <?php echo $data->daily[0]->clouds; ?>°C</span><br>
<span class="min-temperature"> Pressure <?php echo $data->daily[0]->weather->id; ?></span>第一行顯示數(shù)據(jù)正常，但天氣部分中的任何內(nèi)容都無(wú)法顯示任何內(nèi)容。我已經(jīng)看到了刪除所有方括號(hào)的解決方案，但它只需要圍繞天氣部分的括號(hào)。提前致謝

下面的代碼 json_decodes 并回顯云和天氣數(shù)組。'希望能幫助到你。請(qǐng)給出意見(jiàn)。謝謝。
<?php
$data=json_decode( '{"daily":{"dt":1593864000,"sunrise":1593834201,"sunset":1593894929,"temp":{"day":18.47,"min":17.83,"max":18.71,"night":17.83,"eve":18.71,"morn":18.47},"feels_like":{"day":16,"night":13.09,"eve":16.54,"morn":16},"pressure":1006,"humidity":77,"dew_point":14.37,"wind_speed":5.51,"wind_deg":244,"weather":[{"id":500,"main":"Rain","description":"light rain","icon":"10d"}],"clouds":90,"uvi":7.08}}'); # define $data as a stdClass Object
echo $data->daily->clouds;
echo "\n";
# below, weather array is converted into a string
$wa=(array)$data->daily->weather[0];
foreach($wa as $key=> $val){
echo $key."=".$val."; ";
}
?>
輸出：
90
id=500; main=Rain; description=light rain; icon=10d;

在這種情況下，您必須使用json_decode將 json 字符串轉(zhuǎn)換為關(guān)聯(lián)數(shù)組。
$data = '{"daily":{"dt":1593864000,"sunrise":1593834201,"sunset":1593894929,"temp":{"day":18.47,"min":17.83,"max":18.71,"night":17.83,"eve":18.71,"morn":18.47},"feels_like":{"day":16,"night":13.09,"eve":16.54,"morn":16},"pressure":1006,"humidity":77,"dew_point":14.37,"wind_speed":5.51,"wind_deg":244,"weather":[{"id":500,"main":"Rain","description":"light rain","icon":"10d"}],"clouds":90,"uvi":7.08}}';
$decode = json_decode($data,true);
echo '<pre>';
//print_r($decode);
echo $decode['daily']['clouds'].'<br>';
echo $decode['daily']['uvi'].'<br>';
echo $decode['daily']['weather'][0]['id'].'<br>';
echo $decode['daily']['weather'][0]['main'].'<br>'; //These three are from weather array.
echo $decode['daily']['weather'][0]['description'].'<br>';
echo '<pre>';
輸出
90
7.08
500
Rain
light rain
print_r如果您想知道數(shù)組索引是如何工作的，您可以從代碼中使用它，只需將其從注釋中刪除即可。
