前回までのカレンダーは日曜始まりでしたが、今回は月曜始まりに変更。
また、年と月を選択リストにし、直接見たいところへ移動可能に。
左の「<<」ボタンで前月を、右の「>>」ボタンで翌月を表示可能に。
「今月」ボタンを押すと、即座に今月の表示に戻ります。
祝日のデータは、Googleカレンダーから取得したものです。前回は2012年からのデータしか無かったのですが、本日試したら、2010から2016年までの祝日データが取れました。・・・これを元にソース上の連想配列に・・・。
今回は以下のサイトを参考にさせていただきました。
PHPでカレンダー作成(翌月や先月も表示できるタイプ)
HTMLファイル（test_calendar2.html）からインラインフレーム内に呼び出してみました。
<!DOCTYPE html> <html lang="ja"> <head> <title>カレンダー</title> <meta charset="UTF-8"> </head> <body> <div align="center"> <iframe frameborder=0 width=400px height=400px src="cgi-bin/calendar/calendar2.php"></iframe> </div> </body> </html>
カレンダーを表示するPHPファイル（calendar2.php）には、祝日の連想配列 $holidays を入れたので長くなりました。
場所は、上記HTMLファイル内で指定したところです。
