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~
------解决方案--------------------

<?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 
------解决方案--------------------

$s='2013-05-31';<br />$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 />}
