PHP和时间头痛

Question

这是我的函数

function thisProduction($week_start, $week_end, $this){
echo "<h2>Production > $this week (w/c ".$week_start." - ".$week_end.")</h2>";
}

这是我定义参数的地方

$this_week_start = date('Y-m-d',strtotime('this Monday'));
$this_week_end = date('Y-m-d',strtotime('this Sunday'));
$last_week_start = date('Y-m-d',strtotime('last Monday'));
$last_week_end = date('Y-m-d',strtotime('last Sunday'));

我这样称呼这种意志论点

thisProduction($this_week_start, $this_week_end, 'This');
thisProduction($last_week_start, $last_week_end, 'Last');

我想要（以今天的日期2017年1月31日为例）

Production > This week (W/C 2017-01-30 - 2017-02-05)
Production > Last week (W/C 2017-01-23 - 2017-01-29)

昨晚这是"工作"，但今天我得到了这些结果

PRODUCTION > THIS WEEK (W/C 2017-02-06 - 2017-02-05)
PRODUCTION > LAST WEEK (W/C 2017-01-30 - 2017-01-29)

Answer 1

更好地使用monday this week：

$this_week_start = date('Y-m-d',strtotime('monday this week'));
$this_week_end = date('Y-m-d',strtotime('sunday this week'));
$last_week_start = date('Y-m-d',strtotime('monday last week'));
$last_week_end = date('Y-m-d',strtotime('sunday last week'));

今天和昨天的结果：

本周生产> （w/c 2017-01-30 - 2017-02-05）

上周生产> （w/c 2017-01-23 - 2017-01-29）
