求个PHP列出周日期代码

看图片吧，这种列表用PHP怎么写呢？求高人帮帮忙~

回复讨论(解决方案)

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

代码写得很粗糙 

$s='2013-05-31';$current=date("Y-m-d");while($current>=$s){    $ar[]=$current;	$current=date("Y-m-d",strtotime("$current -7 day"));}	for($i=0;$i<count($ar)-1;$i++){	   echo $ar[$i+1].'->'.$ar[$i]."\n";	}

for($i=0,$t=-7; $i<20; $i++,$t-=7) {  echo date('Y-m-d -> ', strtotime("$t day"));  echo date('Y-m-d', strtotime(($t+7)."day")) . '<br>';}

谢谢各位啦...

for($i=0,$t=-7; $i<20; $i++,$t-=7) {  echo date('Y-m-d -> ', strtotime("$t day"));  echo date('Y-m-d', strtotime(($t+7)."day")) . '<br>';}
