PHP

最近看到大家寫PHP寫得很開心,
就也來寫一寫....
結果在發貼的時候還不小心發現blogspot的一個bug....

下面是羅馬數字轉換的代碼....
參考可以....
抄的人考試一定會當掉....

$z="1985";
function abc($a,$b,$c,$d)
{
  switch($a)
  {
    case 1:
      echo $b;
      break;
    case 2:
      echo $b.$b;
      break;
    case 3:
      echo $b.$b.$b;
      break;
    case 4:

      break;
