php 把数字转换成汉字的代码
在一次面试中遇到一个有意思的小算法题:要求将阿拉伯数字转为汉字显示出来(包含单位)。当时虽然实现出来,但是代码写的有点凌乱。所以回家后,重新整理了一下。
直接上实例,写到 千亿上了。
/** * @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);
方法二:
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);
以上所述就是本文的全部内容了,希望大家能够喜欢。
