★今回の反省点。
calendar.phpにおいて、HTML上のPHPを極限までなくしたくて、Modelで全部配列にHTMLタグごと突っ込んでしまったけど、これは間違った書き方。PHPの中にHTMLタグを書かない方がよし。
★今回のお初にお目にかかります。
○$_REQUEST
$_GET、 $_POST そして $_COOKIE の内容をまとめた連想配列。
=>要は$_GETの値も$_POSTの値も拾ってくれるマルチな子。
○PEAR
PHP Extension and Application Repository の略。
PHP４からついてくるようになった、クラスライブラリ（よく使う機能を「クラス」としてまとめたもの）週のこと。
つまりおまけでついてくるようになった便利ツールさん。
