NOAAはfile_get_contentsとsimplexml_load_file()からご要望に応じて403禁止されたHTTPステータスを返されたが、Firefoxはそれがうまく得ることができます。
私は、FireFoxのように見えるカールリクエストを作成しました。
次に、XMLを配列に変換しました。私はオブジェクトではなく配列で作業するほうが好きです。

これは、これを与えました場合によっては最後の日に1つの期間しかないために追加する必要がありました。その場合、値はNULLであり、キー値は$period配列にあります。私はそれを試してみた

。問題は、XMLに4790文字のテキスト 'textContent'という項目が含まれていることだけです。私はポイントを逃している、またはあなたが達成したい目標は何ですか？ – Richard
私はこれを試すときはいつも私の 'textContent'は常に空です。 このXMLファイルから降水量と相対湿度を引き出す必要があります。 私はちょっとPHPに少し新しくなっています。あなたが他の方法をとっていればもっとうまくいくかもしれません。 – Skylit
すべてのデータを見るためにforeachループが追加されました。 – Misunderstood
