PHP将带有小数点的一串阿拉伯数字转换成汉字大写形式，就像转换人民币大写类似。加入了小数点的处理，只要是一连串的数字，不管是否带有小数点，通过本函数都能完美转换。
PHP将阿拉伯数字转换成汉字大写支持小数点<?php
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，则用递归处理小数
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;
}
?>
调用方法<?php
//echo ch_num("582368.2576");
echo ch_num("6935.2058");//输出结果为：陆仟玖佰叁拾伍點贰零伍捌
?>
