利用PHP怎么計算一年有幾周?很多新手對此不是很清楚,為了幫助大家解決這個難題,下面小編將為大家詳細講解,有這方面需求的人可以來學習下,希望你能有所收獲。
下面通過兩種方式實現(xiàn)PHP獲取一年有幾周以及每周開始日期和結(jié)束日期
代碼一:
<?php header("Content-type:text/html;charset=utf-8"); date_default_timezone_set("Asia/Shanghai"); $year = (int)$_GET['year']; $week = (int)$_GET['week']; $weeks = date("W", mktime(0, 0, 0, 12, 28, $year)); echo $year . '年一共有' . $weeks . '周<br />'; if ($week > $weeks || $week <= 0) { $week = 1; } if ($week < 10) { $week = '0' . $week; } $timestamp['start'] = strtotime($year . 'W' . $week); $timestamp['end'] = strtotime('+1 week -1 day', $timestamp['start']); echo $year . '年第' . $week . '周開始時間戳:' . $timestamp['start'] . '<br />'; echo $year . '年第' . $week . '周結(jié)束時間戳:' . $timestamp['end'] . '<br />'; echo $year . '年第' . $week . '周開始日期:' . date("Y-m-d", $timestamp['start']) . '<br />'; echo $year . '年第' . $week . '周結(jié)束日期:' . date("Y-m-d", $timestamp['end']); ?>
代碼二:
<?php header("Content-type:text/html;charset=utf-8"); function getIsoWeeksInYear($year) { $date = new DateTime; $date->setISODate($year, 53); return ($date->format("W") === "53" ? 53 : 52); } function weekday($custom_date) { $week_start = date('d-m-Y', strtotime('this week monday', $custom_date)); $week_end = date('d-m-Y', strtotime('this week sunday', $custom_date)); $week_array[0] = $week_start; $week_array[1] = $week_end; return $week_array; } echo '<br> Weeks in 2013<br>' . getIsoWeeksInYear(2013); $weekday = weekday(strtotime(date('d-m-Y', strtotime('5-8-2013')))); echo '<br> 10-8-2013'; echo '<br>Start: ' . $weekday[0]; echo '<br>End: ' . $weekday[1]; ?>
