PHP開發(fā)之製作簡(jiǎn)單日曆計(jì)算日曆的天數(shù)與樣式
自訂函數(shù)caculate方法,計(jì)算日曆的天數(shù)與樣式。
1)將上個(gè)月的天數(shù)計(jì)算出來,本月第一天的星期不是星期天的話,就需要根據(jù)上個(gè)月的最後一天計(jì)算
2)將本月的天數(shù)遍歷出來,如果是休息天就加上特殊的css樣式
3)將下個(gè)月的天數(shù)計(jì)算出來,分三種情況,星期日、星期六和工作日
<?php function caculate($calendar) { //$calendar 通過threshold方法計(jì)算后的數(shù)據(jù) $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'];//上個(gè)月的最后一天 $year = $calendar['year']; $month = $calendar['month']; $dates = array(); if($firstDayOfWeek != 7) { $lastDays = array(); $current = $lastMonthOfLastDay;//上個(gè)月的最后一天 for ($i = 0; $i < $firstDayOfWeek; $i++) { array_push($lastDays, $current);//添加上一個(gè)月的日期天數(shù) $current--; } $lastDays = array_reverse($lastDays);//反序 foreach ($lastDays as $index => $day) { array_push($dates, array('day' => $day, 'tdclass' => ($index ==0 ?'rest':''), 'pclass' => 'outter')); } } //本月日歷信息 for ($i = 1; $i <= $days; $i++) { $isRest = $this->_checkIsRest($year, $month, $i); //判斷是否是休息天 array_push($dates, array('day' => $i, 'tdclass' => ($isRest ?'rest':''), 'pclass' => '')); } //下月日歷信息 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 <= $length; $i++) { array_push($dates, array('day' => $i, 'tdclass' => ($i==$length ?'rest':''), 'pclass' => 'outter')); } return $dates; } ?>
註:
array_push() 函數(shù)在第一個(gè)參數(shù)的陣列尾部新增一個(gè)或多個(gè)元素,然後傳回新陣列的長(zhǎng)度。
array_reverse() 函數(shù)傳回翻轉(zhuǎn)順序的陣列。
