PHP - 從數組中獲取信息

Question

我試圖從我的氣象站獲取傳感器值。 我得到的 API 在數組中。

我不知道如何只從 ["id"]=> "1549112871" 中獲取 "temp" 數據。 如果我回顯 $sensor["temp"] 我將從整個數組中獲取臨時數據。

// 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 nederbörd senaste 
dygnet"; } else { /* */ }?></h2>

<?php } ?>

<h3><?php echo "Det blåser för tillfället " . $sensor["wgust"] . " m/s";?></h3>

作為您提供的數據，您的數據是一個二維數組。 每個數組都有鍵：“id”，“temp”，......並且您想要獲取具有特定“id”的數組的“temp”值。

如果你想這樣做，你必須遍歷數組以找到與所需“id”匹配的數組：

foreach ($eachSensor as $sensor) {
    if ($sensor['id'] != '1549112871') {
        continue;
    }

    // Your code here...
    // This $sensor has the id value equal to 1549112871
}
