我試圖從我的氣象站獲取傳感器值。我得到的 API 在陣列中。
我不知道如何只從 [“id”]=>“1549112871”中獲取“臨時”資料。如果我 echo $sensor["temp"] 我將從整個陣列中獲取臨時資料。
// Send the request & save response to $resp
$resp = curl_exec($ch);
$jsonResp = json_decode($resp, true);
$eachSensor = $jsonResp["sensor"];
// Close request
curl_close($ch);
foreach ($eachSensor as $sensor) {
?>
<h2><?php if(!empty($sensor["rrate"])) { echo $sensor["rrate"] . " mm nederb?rd senaste
dygnet"; } else { /* */ }?></h2>
<?php } ?>
<h3><?php echo "Det bl?ser f?r tillf?llet " . $sensor["wgust"] . " m/s";?></h3>

uj5u.com熱心網友回復：
作為您提供的資料，您的資料是一個二維陣列。每個陣列都有鍵：“id”、“temp”、...并且您想獲得具有特定“id”的陣列的“temp”值。
如果您想這樣做，您必須遍歷陣列以查找與所需“id”匹配的陣列：
foreach ($eachSensor as $sensor) {
if ($sensor['id'] != '1549112871') {
continue;
}
// Your code here...
// This $sensor has the id value equal to 1549112871
}
