How to convert numbers into Chinese characters in php

This article mainly introduces how to convert numbers into Chinese characters in PHP. Interested friends can refer to it. I hope it will be helpful to everyone.

I encountered an interesting little algorithm question during an interview: I was asked to convert Arabic numerals into Chinese characters and display them (including units). Although it was implemented at that time, the code was a bit messy. So after I got home, I reorganized it.

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

/**
* @author ja颂 
* 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('零', '一', '二', '三', '四', '五', '六', '七', '八', '九');
$chiUni = array('','十', '百', '千', '万', '亿', '十', '百', '千');
$chiStr = '';
$num_str = (string)$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
$chiStr = '';//拼接结果
if ($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 ? '' : $chiNum[$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);

Method 2:

1 and $str[$i]+$str[$i-1] == 0){
                $out[$i] = '';
            }
                if($i%4 == 0){
                $out[$i] .= $unit[4+floor($i/4)];
            }
        }
    }
    $retval = join('',array_reverse($out)) . $retval;
    return $retval;
 }
 //实例调用=====================================================
$num = '0123648867.789';
echo $num,'
';
 //普通数字的汉字表示
echo '普通:',number2chinese($num,false),'';
echo '
';
 //金额汉字表示
echo '金额(简体):',number2chinese($num,true),'';
echo '
';
echo '金额(繁体):',number2chinese($num,true,false);
