Two ways to convert numbers to Chinese in PHP

Two methods of converting numbers to Chinese in php

Go directly to the example and write it to 100 billion.

<?php
/**
* 把数字1-1亿换成汉字表述，如：123->一百二十三
* @param [num] $num [数字]
* @return [string] [string]
*/
function numToWord($num)
{
$chiNum = array(&#39;零&#39;, &#39;一&#39;, &#39;二&#39;, &#39;三&#39;, &#39;四&#39;, &#39;五&#39;, &#39;六&#39;, &#39;七&#39;, &#39;八&#39;, &#39;九&#39;);
$chiUni = array(&#39;&#39;,&#39;十&#39;, &#39;百&#39;, &#39;千&#39;, &#39;万&#39;, &#39;亿&#39;, &#39;十&#39;, &#39;百&#39;, &#39;千&#39;);
 
$chiStr = &#39;&#39;;
 
$num_str = (string)$num;
 
$count = strlen($num_str);
$last_flag = true; //上一个 是否为0
$zero_flag = true; //是否第一个
$temp_num = null; //临时数字
 
$chiStr = &#39;&#39;;//拼接结果
if ($count == 2) {//两位数
$temp_num = $num_str[0];
$chiStr = $temp_num == 1 ? $chiUni[1] : $chiNum[$temp_num].$chiUni[1];
$temp_num = $num_str[1];
$chiStr .= $temp_num == 0 ? &#39;&#39; : $chiNum[$temp_num]; 
}else if($count > 2){
$index = 0;
for ($i=$count-1; $i >= 0 ; $i--) { 
$temp_num = $num_str[$i];
if ($temp_num == 0) {
if (!$zero_flag && !$last_flag ) {
$chiStr = $chiNum[$temp_num]. $chiStr;
$last_flag = true;
}
}else{
$chiStr = $chiNum[$temp_num].$chiUni[$index%9] .$chiStr;
 
$zero_flag = false;
$last_flag = false;
}
$index ++;
}
}else{
$chiStr = $chiNum[$num_str[0]]; 
}
return $chiStr;
}
 
$num = 150;
echo numToWord($num);

The output result shows:

一百五十

Method 2:

<?php
 /**
* 数字转换为中文

* @param  integer $mode 模式[true:金额（默认）,false:普通数字表示]
* @param  boolean $sim 使用小写（默认）
* @return string
*/
 function number2chinese($num,$mode = true,$sim = true){
    if(!is_numeric($num)) return &#39;含有非数字非小数点字符！&#39;;
    $char    = $sim ? array(&#39;零&#39;,&#39;一&#39;,&#39;二&#39;,&#39;三&#39;,&#39;四&#39;,&#39;五&#39;,&#39;六&#39;,&#39;七&#39;,&#39;八&#39;,&#39;九&#39;)

    $unit    = $sim ? array(&#39;&#39;,&#39;十&#39;,&#39;百&#39;,&#39;千&#39;,&#39;&#39;,&#39;万&#39;,&#39;亿&#39;,&#39;兆&#39;)

        $dec = strval(round($dec,2));
        if($mode){
            $retval .= "{$char[$dec[&#39;0&#39;]]}角{$char[$dec[&#39;1&#39;]]}分";
        }else{
            for($i = 0,$c = strlen($dec);$i < $c;$i++) {
                $retval .= $char[$dec[$i]];
            }
        }
    }
    //整数部分
    $str = $mode ? strrev(intval($num)) : strrev($num);
    for($i = 0,$c = strlen($str);$i < $c;$i++) {
        $out[$i] = $char[$str[$i]];
        if($mode){
            $out[$i] .= $str[$i] != &#39;0&#39;? $unit[$i%4] : &#39;&#39;;
                if($i>1 and $str[$i]+$str[$i-1] == 0){
                $out[$i] = &#39;&#39;;
            }
                if($i%4 == 0){
                $out[$i] .= $unit[4+floor($i/4)];
            }
        }
    }
    $retval = join(&#39;&#39;,array_reverse($out)) . $retval;
    return $retval;
 }
 //实例调用=====================================================
$num = &#39;0123648867.789&#39;;
echo $num,&#39;<br>&#39;;
 //普通数字的汉字表示
echo &#39;普通:&#39;,number2chinese($num,false),&#39;&#39;;
