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);
