PHP Homemade Calendar _php Tutorial

PHP Homemade Calendar

First, calculate data 1, new A Calendar Class 2, initialize two drop-down boxes of data, year and month 3, initialize the year and month to search for, and calculate the data information for each day of the calendar, including CSS, the number of days to copy code Threshold ($year, $month);//Get each boundary value $caculate = $util->caculate ($calendar);//Calculate calendar days with style $draws = $util->draw ($ caculate);//Draw the table, set the table in the TR and td?> copy code two, HTML display 1, the background color of the rest day is different, not the current search years of the days of the font color is also different 2, the Div do the initialization of the year and the Month drop-down box operation, and select the current date to search 3, the data has been calculated, which TD belongs to which TR is also done, directly print the table can be copied code > > TD Width= "14%" > a !--? php foreach ($draws as $draw) {?--> !--? php foreach ($draw as $date) {?-->

Day	two	three	four	five	six

Copy code three, Calendar Class 1, Threshold method, generate the calendar of each boundary value 1) Calculate the total number of days of the Month 2) calculate the first day of the month and the last day, each week a few 3) calculate the first date in the calendar and the last date copy code/** * @depreca Ted generates various boundary values for the calendar * @param string $year * @param string $month * @return Array */function threshold ($year, $month) {$firstD ay = mktime (0, 0, 0, $month, 1, $year); $lastDay = Strtotime (' +1 month-1 Day ', $firstDay); Number of days $days = Date ("T", $firstDay); Gets the first day of the Week $firstDayOfWeek = Date ("N", $firstDay); Get the last day of the week $lastDayOfWeek = Date (' N ', $lastDay); Last one months $lastMonthDate = Strtotime ('-1 day ', $firstDay); $lastMonthOfLastDay = Date (' d ', $lastMonthDate); The first day of the next one months $nextMonthDate = Strtotime (' +1 days ', $lastDay); $nextMonthOfFirstDay = Strtotime (' +1 Day ', $lastDay); The first date of the calendar if ($firstDayOfWeek = = 7) $firstDate = $firstDay; else $firstDate = strtotime ('-'. $firstDayOfWeek.
