php 阿拉伯数字转中文数字 方法

　　<?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，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 $retval;
}
//echoch_num("12345006789001.123");
//echo ch_num("880079.1234");
echoch_num("300045.0123");
　　这个方法更为优秀一些.
　　function toCNcap($data){
$capnum=array("零","壹","贰","叁","肆","伍","陆","柒","捌","玖");

}
$cncap .= $chiao.$cent."整";
$cncap=preg_replace("/(零)+/","//1",$cncap); //合并连续“零”
return $cncap;
}
