PHP 自制日历_PHP教程

threshold($year, $month);//获取各个边界值$caculate = $util->caculate($calendar);//计算日历的天数与样式$draws = $util->draw($caculate);//画表格，设置table中的tr与td?>复制代码

二、html展示

1、休息天的背景色是不同的，不是当前搜索年月的天数字体颜色也是不同的2、div中做初始化年份与月份的下拉框的操作，并选中当前要搜索的年月3、数据已计算好，哪个td属于哪个tr也已做好，直接将table打印出来即可复制代码php foreach($years as $data) {?>php }?php foreach($months as $data) {?>php }?日一二三四五六复制代码

三、Calendar类

1、threshold方法，生成日历的各个边界值

1)计算这个月总天数2)计算这个月第一天与最后一天，各是星期几3)计算日历中的第一个日期与最后一个日期复制代码/*** @deprecated 生成日历的各个边界值* @param string $year* @param string $month* @return array*/ function threshold($year, $month) {$firstDay = mktime(0, 0, 0, $month, 1, $year);$lastDay = strtotime('+1 month -1 day', $firstDay);//取得天数$days = date("t", $firstDay);//取得第一天是星期几$firstDayOfWeek = date("N", $firstDay);//获得最后一天是星期几$lastDayOfWeek = date('N', $lastDay);//上一个月最后一天$lastMonthDate = strtotime('-1 day', $firstDay);$lastMonthOfLastDay = date('d', $lastMonthDate);//下一个月第一天$nextMonthDate = strtotime('+1 day', $lastDay);$nextMonthOfFirstDay = strtotime('+1 day', $lastDay);//日历的第一个日期if($firstDayOfWeek == 7)$firstDate = $firstDay;else$firstDate = strtotime('-'. $firstDayOfWeek .' day', $firstDay);//日历的最后一个日期if($lastDayOfWeek == 6)$lastDate = $lastDay;elseif($lastDayOfWeek == 7)$lastDate = strtotime('+6 day', $lastDay);else$lastDate = strtotime('+'.(6-$lastDayOfWeek).' day', $lastDay);return array('days' => $days,'firstDayOfWeek' => $firstDayOfWeek,'lastDayOfWeek' => $lastDayOfWeek,'lastMonthOfLastDay' => $lastMonthOfLastDay,'firstDate' => $firstDate,'lastDate' => $lastDate,'year' => $year,'month' => $month);}复制代码

2、caculate方法，计算日历的天数与样式

1)将上个月的天数计算出来，本月第一天的星期不是星期天的话，就需要根据上个月的最后一天计算2)将本月的天数遍历出来，如果是休息天就加上特殊的css样式3)将下个月的天数计算出来，分三种情况，星期日、星期六和工作日复制代码/*** @author Pwstrick* @param array $calendar 通过threshold方法计算后的数据* @deprecated 计算日历的天数与样式*/ function caculate($calendar) {$days = $calendar['days'];$firstDayOfWeek = $calendar['firstDayOfWeek'];//本月第一天的星期$lastDayOfWeek = $calendar['lastDayOfWeek'];//本月最后一天的星期$lastMonthOfLastDay = $calendar['lastMonthOfLastDay'];//上个月的最后一天$year = $calendar['year'];$month = $calendar['month'];$dates = array();if($firstDayOfWeek != 7) {$lastDays = array();$current = $lastMonthOfLastDay;//上个月的最后一天for ($i = 0; $i array_push($lastDays, $current);//添加上一个月的日期天数$current--;}$lastDays = array_reverse($lastDays);//反序foreach ($lastDays as $index => $day) {array_push($dates, array('day' => $day, 'tdclass' => ($index ==0 ?'rest':''), 'pclass' => 'outter'));}}//本月日历信息for ($i = 1; $i$isRest = $this->_checkIsRest($year, $month, $i);//判断是否是休息天array_push($dates, array('day' => $i, 'tdclass' => ($isRest ?'rest':''), 'pclass' => ''));}//下月日历信息if($lastDayOfWeek == 7) {//最后一天是星期日$length = 6;}elseif($lastDayOfWeek == 6) {//最后一天是星期六$length = 0;}else {$length = 6 - $lastDayOfWeek;}for ($i = 1; $i array_push($dates, array('day' => $i, 'tdclass' => ($i==$length ?'rest':''), 'pclass' => 'outter'));}return $dates;}复制代码

3、draw方法，画表格，设置table中的tr与td

1)数据将要用table标签来显示，所以这里要将各个tr下面的td排列好2)$index % 7 == 0 计算表格每行的第一列3)$index % 7 == 6 || $index == ($length-1) 计算每行的最后一列，或$caculate的最后一个数据4)将中间行添加到$tr中，就是每一行的array复制代码/*** @author Pwstrick* @param array $caculate 通过caculate方法计算后的数据* @deprecated 画表格，设置table中的tr与td*/ function draw($caculate) {$tr = array();$length = count($caculate);$result = array();foreach ($caculate as $index => $date) {if($index % 7 == 0) {//第一列$tr = array($date);}elseif($index % 7 == 6 || $index == ($length-1)) {array_push($tr, $date);array_push($result, $tr);//添加到返回的数据中$tr = array();//清空数组列表}else {array_push($tr, $date);}}return $result;}http://www.bkjia.com/PHPjc/885672.html www.bkjia.com true http://www.bkjia.com/PHPjc/885672.html TechArticle PHP 自制日历 一、计算数据 1、new一个Calendar类 2、初始化两个下拉框中的数据，年份与月份 3、初始化要搜索的年份和月份 4、计算得出日历...
