以下PHP代码将数字转换为书面文字。这适用于像5250这样的整数，但是，如果给出带小数的数字，则不能正确解析数字。
450将输出＆＃34;四百五十＆＃34;。然而，450.5将输出＆＃34;四千五百五十。＆＃34;它应该是四百五十五点。
我搜索了网络，但我无法提出解决方案。有人可以建议更正吗？

问题中的代码不会在小数点上分割数字;它只是查看字符串中的所有数字。所以，当然它不起作用。为了使其正常工作：
.45变为point four five。答案 1 :(得分：0)
这是一个有效的解决方案。它可能无法完全满足您的尝试，但它应该是一个良好的开端。关键是通过一次递归调用重新使用您的工作。如果再次为小数点后的数字调用函数，则可以合并结果：
function inr($number, $doOtherWords = true){
//A function to convert numbers into words.
$words = array(
'0'=> '' ,'1'=> 'one' ,'2'=> 'two' ,'3' => 'three','4' => 'four','5' => 'five',

'11' => 'eleven','12' => 'twelve','13' => 'thirteen','14' => 'fouteen','15' => 'fifteen',
'16' => 'sixteen','17' => 'seventeen','18' => 'eighteen','19' => 'nineteen','20' => 'twenty',
'30' => 'thirty','40' => 'fourty','50' => 'fifty','60' => 'sixty','70' => 'seventy',
'80' => 'eighty','90' => 'ninty');
//First find the length of the number

//Initialize an empty array

// Save off if we have a decimal in a variable. Assume we don't

//Store all received numbers into an array

首先确定整数和小数点后的数字，使用$number=explode(".",$number);将两个数字分成一个数组。
$ number [0]将是您的整数，$ number [1]将是小数点后的数字。
function inr($number[0]){
/* Your function for the whole number */
}
function inr2($number[1]){
/* Your function for the number after the decimal point */
}
