本程序将中文日期输出为2001-12-23，并很好解决了“十”的问题，如“十一”和“二十一”中“十”的处理！稍加修改可改为函数。
<?
$str="二零○一年十二月二十三日";
echo $str."<p>";
$flag=0;
$cn=array("一","二","三","四","五","六","七","八","九","十","零","○");
$num=array("1","2","3","4","5","6","7","8","9","","0","0");
$len=strlen($str);
for ($i=0;$i<$len;$i+=2)
{
   $array_str[$i]=substr($str,$i,2);
   $cout=0;
   while($cout<count($cn))
   {
     if ($array_str[$i]==$cn[$cout])
     {
       if ($flag==1)
         echo "-";
       if (($array_str[$i]=="十") and ($flag==1))
       {
         $temp[$cout]="1";
         echo $temp[$cout];
         $flag=2;break;
       }
       $temp[$cout]=$num[$cout];
       echo $temp[$cout];
       $flag=2;
       break;
     }
     else
     {
       if (count($cn)==$cout+1)
          $flag=1;
     }
     $cout++;
   }
}
?>
