最近接了一个项目,其中有一需求是用php获取一年有几周以及每周开始日期和接触日期。在网上找些资料没有合适的,于是自己做了一份,下面通过两种方式实现php获取一年有几周以及每周开始日期和结束日期
代码一:
<?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 . '周开始时间戳:' . $timestamp['start'] . '<br />'; echo $year . '年第' . $week . '周结束时间戳:' . $timestamp['end'] . '<br />'; echo $year . '年第' . $week . '周开始日期:' . date("y-m-d", $timestamp['start']) . '<br />'; echo $year . '年第' . $week . '周结束日期:' . date("y-m-d", $timestamp['end']); ?>
代码二:
<?php header("content-type:text/html;charset=utf-8"); function getisoweeksinyear($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]; ?>
