最近因需要,寫了個「阿拉伯數字轉中文數字的函數」。搜尋了精華區只見到一個類似的。
感覺到我的演算法不錯,所以貼出來分享如果要用於金額的轉換,對小數部分的處理要做一下修改
function ch_num($num,$mode = true) {
$char = array("零","壹","贒","叁","肆","伍","陸","柒","捌","玖" );
$dw = array("","拾","佰","仟","","萬","億","兆");
$dec = "點" ;
$retval = "";
if($mode)
preg_match_all("/^0*(d*).?(d*)/",$num, $ar ) ;
else
preg_match_all("/(d*).?(d*)/",$num, $ar);
if($ar[2][0] ! = "")
$retval = $dec . ch_num($ar[2][0],false); //如果有小數,先遞歸處理小數
if($ar[1][0] ! = "") {
$str = strrev($ar[1][0]);
for($i=0;$i
if($mode) {
$out[$i] .= $str[$i] != "0"? $ dw[$i%4] : "";
if($str[$i] $str[$i-1] == 0)
if($i%4 == 0)
$out[$i] .= $dw[4 floor($i/4)];
}
"",array_reverse($out)) . $retval;
}
return $retval;
}
//echo ch_num("12345006789001.123"); ch_num("880079.1234");
?>
