PHPで祝日表示付きカレンダーの作成。

2010.05.16 / Labs

PEAR
PHP

PHPのPEARライブラリを使って、祝日の表示を加えたカレンダーの作成方法です。
カレンダーの作成には「Calendar」ライブラリ、祝日の取得には「Date_Holidays_Japan」ライブラリを利用しています。

<?php
require_once("Calendar/Month/Weekdays.php");
require_once("Date/Holidays.php");

$current_year = date("Y");
$current_month = date("n");
$calMonth = new Calendar_Month_Weekdays($current_year, $current_month, 0);//第3引数の0は週の最初を日曜に
$calMonth->build();
$ja = "data/Date_Holidays_Japan/lang/Japan/ja_JP.xml";
$dh = &Date_Holidays::factory("Japan", $current_year, "ja_JP");
$dh->addTranslationFile($ja, "ja_JP");
$holidays = array();

//祝日の月日をキーに祝日名を配列に格納
foreach ($dh->getHolidays() as $value) {
	$holidays[$value->getDate()->format("%m%d")] = $value->getTitle();
}

echo "<h2>".$current_year."年".$current_month."月"."</h2>\n";
echo "<table class=\"calendar\">\n"; 
echo "<thead>\n"; 
echo "<tr><th>日</th><th>月</th><th>火</th><th>水</th><th>木</th><th>金</th><th>土</th></tr>\n"; 
echo "</thead>\n"; 
echo "<tbody>\n"; 

while ($day = $calMonth->fetch()) { 
	if ($day->isFirst()) {
		echo '<tr>';
	}
	if ($day->isEmpty()) { 
		echo "<td>&nbsp;</td>";
	} else { 
		$date = sprintf("%02d",$day->thisMonth()).sprintf("%02d",$day->thisDay());
		if (array_key_exists($date, $holidays)) {
			echo "<td class=\"holiday\">";//祝日のとき
		} else if ($day->isFirst()) {
			echo "<td class=\"sun\">";//週の最初（日曜）のとき
		} else if ($day->isLast()) {
			echo "<td class=\"sat\">";//週の最後（土曜）のとき
		} else {
			echo "<td>";
		}
		echo "<span class=\"day\">".$day->thisDay()."</span>";
		
		//祝日に該当する月日の場合、祝日名を出力
		if (array_key_exists($date, $holidays)) {
			echo "<span class=\"holiday\">".$holidays[$date]."</span>";
		}
		echo "</td>";
	} 
	if ($day->isLast()) { 
		echo "</tr>\n";
	} 
} 
echo "</tbody>\n";
echo "</table>\n";
?>

<?php

require_once("Calendar/Month/Weekdays.php");

require_once("Date/Holidays.php");

$current_year = date("Y");

$current_month = date("n");

//祝日の月日をキーに祝日名を配列に格納

foreach ($dh->getHolidays() as $value) {

$holidays[$value->getDate()->format("%m%d")] = $value->getTitle();

echo "<h2>".$current_year."年".$current_month."月"."</h2>\n";

echo "<table class=\"calendar\">\n";

echo "<thead>\n";

echo "</thead>\n";

echo "<tbody>\n";

while ($day = $calMonth->fetch()) {

if ($day->isFirst()) {

echo '<tr>';

}

if ($day->isEmpty()) {

echo "<td> </td>";

} else {

$date = sprintf("%02d",$day->thisMonth()).sprintf("%02d",$day->thisDay());

if (array_key_exists($date, $holidays)) {

echo "<td class=\"holiday\">";//祝日のとき

} else if ($day->isFirst()) {

echo "<td class=\"sun\">";//週の最初（日曜）のとき

} else if ($day->isLast()) {

echo "<td class=\"sat\">";//週の最後（土曜）のとき

} else {

echo "<td>";

}

echo "<span class=\"day\">".$day->thisDay()."</span>";

//祝日に該当する月日の場合、祝日名を出力

if (array_key_exists($date, $holidays)) {

echo "<span class=\"holiday\">".$holidays[$date]."</span>";

}

echo "</td>";

}

if ($day->isLast()) {

echo "</tr>\n";

}

echo "</tbody>\n";

echo "</table>\n";

あらかじめ祝日の月日、名称を配列に格納しておき、カレンダー生成のループの中で、祝日の判定を行っています。
