PHPビルトインサーバーで特定のIPアドレスにサーバーを公開するには、コマンドの最後にIPアドレスとポート番号を指定します。具体的には「php -S IPアドレス:ポート番号」という形式で実行します。IPアドレスを指定しない場合、デフォルトで127.0.0.1（ローカルホスト）にバインドされます。
php -S 192.168.11.8:8000 -t php_public_html
test.php:: getをうけてsample.txtに書き込む 測定結果表示はtest2.phpでおこなう
<?php echo "Hello World!\n"; $data="temp=".$_GET['temp']." humidity=".$_GET['humidity']; ・・・文字連結が特殊！ echo $data; file_put_contents("sample.txt", $data); ?>
