PHP – Grab info from array

Im trying to get sensor value from my weather station. The API i get is in the array.

I can’t figure out how to only grab “temp” data from [“id”]=> “1549112871”. If I echo $sensor[“temp”] I will get temp data from whole array.

// 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>

array(16) { ["id"]=> string(10) "1547443848" ["name"]=> string(9) "Friggebod" 
["lastUpdated"]=> int(1640767771) ["ignored"]=> int(0) ["client"]=> string(6) "592885"

Answer

As your provided data, your data is a 2-dimensions array. Each array will have the keys: “id”, “temp”,… And you want to get the “temp” value of the array that has a specific “id”.

If you want to do so, you must loop through the array to find which array matched the desired “id”:

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

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