<?php<br>
//打印周五<br>
$week = getdate();<br>
//echo $week['wday'];<br>
if($week['wday']==5)<br>
//echo $week['year'].'年'.$week['mon'].'月'.$week['mday'].'日';<br>
//echo $week[year].'年'.$week[mon].'月'.$week[mday].'日';<br>
<br>
for($i=1;$i<=20;$i++)<br>
{<br>
$j=$i*-7;<br>
$k=$j+7;<br>
echo date("Y年m月d日",strtotime($j." days"));<br>
echo "->".date("Y年m月d日",strtotime($k." days"));<br>
echo "<br />";<br>
}<br>
?>代码写得很粗糙

$s='2013-05-31';<br>
$current=date("Y-m-d");<br>
while($current>=$s){<br>
$ar[]=$current;<br>
$current=date("Y-m-d",strtotime("$current -7 day"));<br>
}<br>
for($i=0;$i<count($ar)-1;$i++){<br>
echo $ar[$i+1].'->'.$ar[$i]."\n";<br>
}------解决方案--------------------
for($i=0,$t=-7; $i<20; $i++,$t-=7) {<br>
echo date('Y-m-d -> ', strtotime("$t day"));<br>
echo date('Y-m-d', strtotime(($t+7)."day")) . '<br>';<br>
}
