日期函数
以php实现 一个函数,使它可以根据传入的日期字符串(如2012-03-02)来返回那一天所在周是从哪一天到哪一天?留意跨月和闰年、闰月的情况。
------解决方案--------------------

print_r(between('2012-03-02'));<br /><br />function between($s) {<br />  $t = is_numeric($s) ? $s : strtotime($s);<br />  $w = date('w', $t);<br />  return array(<br />    date('Y-m-d', strtotime("-$w day",$t)),<br />    date('Y-m-d', strtotime((6-$w).' day', $t))<br />  );<br />}
Array
(
    [0] => 2012-02-26
    [1] => 2012-03-03
)
