今天总算有点空，抽时间写了一个类，把数字转换成英语或汉语表达，用法很简单。下面是代码及演示：
文件：textnumber.class.php
代码:
<?php
if(!defined('_IN_APP')) exit;
class TextNumber
{
var $resource = null;
var $number = 0;
var $groupLength = 3;
var $wordSeperated = true;
function setResource($resource = null){
$this->resource = $resource;
}
function setNumber($number){
$this->number = $number;
}
function setWordSeperated($seperated){
$this->wordSeperated = $seperated;
}
function split_number(&$sign, &$int, &$fraction){
list($int, $fraction) = explode('.', $this->number);
$sign = '';
if ($int{0} == '-'){
$sign = '-';
$int = substr($int, 1);
}
$int = preg_replace('/[^0-9]/', '', $int);
$int = preg_replace('/^[0]+/', '', $int);
$int = ($int == '')? '0' : $int;
$fraction = preg_replace('/[^0-9]/', '', $fraction);
if (preg_match('/^0*$/', $fraction))
$fraction = '';
}
function split_group($int){
$int = strrev($int);
$int = chunk_split($int, $this->groupLength, ',');
$int = substr(strrev($int), 1);
return $int;
}
function addSeperator($word = ''){
if ($this->wordSeperated){
if ($word != '')
$word .= ' ';
}
return $word;
}
function trans_sign($sign){
if ($sign == '-'){
if (isset($this->resource['group']['-']))
return $this->addSeperator($this->resource['group']['-']);
else
return '-';
}else{
return '';
}
}
function trans_int($int){
return $this->split_group($int);
}
function trans_dec_point($fraction = 0){
if (isset($this->resource['group']['.'])){
$point = $this->resource['group']['.'];
$point = $this->addSeperator($point);
}else{
$point = '.';
}
return ($fraction == 0)? '' : $point;
}
function trans_fraction($fraction){
return ($fraction == 0)? '' : $fraction;
}
function getText(){
$this->split_number($sign, $int, $fraction);
$ssign = $this->trans_sign($sign);
$sint = $this->trans_int($int);
$spoint = $this->trans_dec_point($fraction);
$sfrac = $this->trans_fraction($fraction);
return trim($ssign.$sint.$spoint.$sfrac);
}
}
