How to convert amount to uppercase in php

php method to convert amount to uppercase: first define the Chinese amount characters that need to be converted; then define the judgment conditions and loop out them, and convert them into Chinese characters in turn; then define the judgment conditions and calculate the converted Chinese characters The length is used as a judgment loop; finally, unnecessary characters are processed and complete Chinese characters are returned.

           $c2 = "分角元拾佰仟万拾佰仟亿";

                      $p1 = substr($c1, 3 * $n, 3);    
                      $p2 = substr($c2, 3 * $i, 3);    
                      if ($n != '0' || ($n == '0' && ($p2 == '亿' || $p2 == '万' || $p2 == '元'))) {        
                                 $c = $p1 . $p2 . $c;    
                      } else {        
                                 $c = $p1 . $c;    
                      }    
                      $i = $i + 1;    
                      //去掉数字最后一位了    
                      $num = $num / 10;    
                      $num = (int) $num;    
                      //结束循环    
                      if ($num == 0) {        
                                 break;    
                      }
           }
           $j = 0;
           $slen = strlen($c);
           while ($j < $slen) {    
                      //utf8一个汉字相当3个字符    
                      $m = substr($c, $j, 6);    
                      //处理数字中很多0的情况,每次循环去掉一个汉字“零”    
                      if ($m == &#39;零元&#39; || $m == &#39;零万&#39; || $m == &#39;零亿&#39; || $m == &#39;零零&#39;) {        
                                 $left = substr($c, 0, $j);        
                                 $right = substr($c, $j + 3);        
                                 $c = $left . $right;        
                                 $j = $j - 3;        
                                 $slen = $slen - 3;    
                      }    
                      $j = $j + 3;
           }
           //这个是为了去掉类似23.0中最后一个“零”字
           if (substr($c, strlen($c) - 3, 3) == &#39;零&#39;) {    
                      $c = substr($c, 0, strlen($c) - 3);
           }
                      //将处理的汉字加上“整”if (empty($c)) {    
                      return "零元整";
           } else {    
                      return $c . "整";
           }
}

The return effect after conversion of this method is as follows

First define the Chinese amount characters that need to be converted

$c1 = "Zero One Two Three Four Five Lu Seven Eighty Nine";

$ c2 = "One hundred thousand yuan one hundred million yuan in cents";

The definition is as shown in the picture

##Then judge the accuracy of the amount

//精确到分后面就不要了，所以只留两个小数位
$num = round($num, 2);
//将数字转化为整数
$num = $num * 100;
if (strlen($num) > 10) {    
           return "金额太大，请检查";
}

Then define the judgment conditions and loop out, and convert them into Chinese characters in turn

$i = 0;
           $c = "";
           while (1) {    
                      if ($i == 0) {    
                                 //获取最后一位数字        
                                 $n = substr($num, strlen($num) - 1, 1);    
                      } else {        
                                 $n = $num % 10;    
                      }    
                      //每次将最后一位数字转化为中文    
                      $p1 = substr($c1, 3 * $n, 3);    
                      $p2 = substr($c2, 3 * $i, 3);    
                      if ($n != '0' || ($n == '0' && ($p2 == '亿' || $p2 == '万' || $p2 == '元'))) {        
                                 $c = $p1 . $p2 . $c;    
                      } else {        
                                 $c = $p1 . $c;    
                      }    $i = $i + 1;    
                      //去掉数字最后一位了    
                      $num = $num / 10;    
                      $num = (int) $num;    
                      //结束循环    
                      if ($num == 0) {        
                                 break;    
                      }
           }

Define the judgment conditions and convert the Calculate the length of Chinese characters as a judgment loop

$j = 0;
$slen = strlen($c);
while ($j < $slen) {    
           //utf8一个汉字相当3个字符    
           $m = substr($c, $j, 6);    
           //处理数字中很多0的情况,每次循环去掉一个汉字“零”    
           if ($m == &#39;零元&#39; || $m == &#39;零万&#39; || $m == &#39;零亿&#39; || $m == &#39;零零&#39;) {  
                      $left = substr($c, 0, $j);        
                      $right = substr($c, $j + 3);        
                      $c = $left . $right;        
                      $j = $j - 3;        
                      $slen = $slen - 3;    
           }    
           $j = $j + 3;
}

Finally process unnecessary characters and return complete Chinese characters

if (substr($c, strlen($c) - 3, 3) == '零') {    
           $c = substr($c, 0, strlen($c) - 3);
}
//将处理的汉字加上“整”
if (empty($c)) {    
           return "零元整";
} else {    
           return $c . "整";
}

Notes

Pay attention to encoding issues during the conversion process

This method is only used to convert digital amounts into Chinese amounts
