WU api を使用して、1 時間ごとの気象データを取得します。API は、1 時間ごとに複数の値を持つ Json を返します。必要なものを照会したいと思います。

{
  "response": {
  "version":"0.1",
  "termsofService":"http://www.wunderground.com/weather/api/d/terms.html",
  "features": {
  "hourly": 1
  }
    }
        ,
    "hourly_forecast": [
        {
        "FCTTIME": {
        "hour": "13","hour_padded": "13","min": "00","min_unpadded": "0","sec": "0","year": "2015","mon": "12","mon_padded": "12","mon_abbrev": "Dec","mday": "30","mday_padded": "30","yday": "363","isdst": "0","epoch": "1451509200","pretty": "1:00 PM PST on December 30, 2015","civil": "1:00 PM","month_name": "December","month_name_abbrev": "Dec","weekday_name": "Wednesday","weekday_name_night": "Wednesday Night","weekday_name_abbrev": "Wed","weekday_name_unlang": "Wednesday","weekday_name_night_unlang": "Wednesday Night","ampm": "PM","tz": "","age": "","UTCDATE": ""
        },
        "temp": {"english": "60", "metric": "16"},
        "dewpoint": {"english": "34", "metric": "1"},
        "condition": "Clear",
        "icon": "clear"
        }
        ,
        {
        "FCTTIME": {
        ...
        }
        ,
        "FCTTIME": {
        ...
        },
        ... more FCTTIME
   ]
}

hourly_forecastこれは配列として取得する私のコードです:

$jsonRequest    = file_get_contents("weather.json");
$data           = json_decode($jsonRequest, true);

$array   = @$data['hourly_forecast'];

tempとconditionを取得する必要があり"hour": "13"ます。したがって、PHP は次のように出力します。The weather is $condition with $temp degree.

最初にオブジェクトを配列に変換しないでください。その必要はありません。

だから変える$data = json_decode($jsonRequest, true);

に$data = json_decode($jsonRequest);

$data->hourly_forecast次に、このように必要な特定の時間を探して配列をループします

foreach( $data->hourly_forecast as $forecast ) {
    if ( $forecast->FCTTIME->hour == 13 ) {
        echo 'The time  ' . $forecast->FCTTIME->hour.PHP_EOL;
        echo 'The temp F' . $forecast->temp->english.PHP_EOL;
        echo 'The temp C' . $forecast->temp->metric.PHP_EOL;
        echo 'The condition ' . $forecast->condition.PHP_EOL;

        // if this is all you need, stop looping
        break;
    }
}

時間ごとの予測のセットをループできるはずです。探している時間に一致する予測が見つかったら、その予測から必要な値を取得して、ループから抜け出します。

foreach ($data['hourly_forecast'] as $forecast) {
    if ($forecast['FCTTIME']['hour'] == 13) {
        $condition = $forecast['condition'];
        $temp = $forecast['temp'];
        break;
    }
}
