一个阿拉伯数字转中文数字的函数

一个阿拉伯数字转中文数字的函数

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<?phpfunction 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<strlen($str);$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");?>
