求个PHP列出周日期代码

Question

看图片吧，这种列表用PHP怎么写呢？求高人帮帮忙~

Answer 1

<?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 

Answer 2

$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";
}

Answer 3

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>';
}
