最近因需要,写了个“阿拉伯数字转中文数字的函数”。搜索了精华区只见到一个类似的。 感觉到我的算法不错,所以贴出来共享一下 如果要用于金额的转换,对小数部分的处理要做一下修改 function ch_num($num,$mode=true) { $char = array("零","壹","贰","叁","肆","伍","陆","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); //如果有小数,先递归处理小数 if($ar[1][0] != "") { $str = strrev($ar[1][0]); for($i=0;$i$out[$i] = $char[$str[$i]]; if($mode) { $out[$i] .= $str[$i] != "0"? $dw[$i%4] : ""; if($str[$i]+$str[$i-1] == 0) $out[$i] = ""; if($i%4 == 0) $out[$i] .= $dw[4+floor($i/4)];} } $retval = join("",array_reverse($out)) . $retval;} return $retval;} //echo ch_num("12345006789001.123"); //echo ch_num("880079.1234"); echo ch_num("300045.0123"); ?> |
