php RMB lowercase to uppercase function, not Limited length, accurate to minutes

When printing invoices or displaying bills, we often need to convert the amount of RMB from lowercase to uppercase. The following is a function I improved, which supports the following features:

• Supports astronomical numbers, the integer digits can theoretically be infinitely long;

• Supports decimals, for currency, it is generally accurate to two decimal places , you can set whether the decimal places are rounded;

• Supports custom currency units. Some systems require the capital to be "round", and some require "yuan", which can be customized;

• Supports integers ending in 0 and customizing numbers containing decimals with "zero" at the end. For example, some systems require that a number like 1960.30 be converted to uppercase to be "One Thousand Nine Hundreds Lu Shi Yuan Three" "Jiao", while some systems require "One thousand, nine hundred, ten yuan and three cents". In both cases, they are correct according to the "basic regulations for correctly filling in bills and settlement vouchers", and can now be customized.

/** 
 * 人民币小写转大写 
 * 
 * @param string $number 数值 
 * @param string $int_unit 币种单位，默认"元"，有的需求可能为"圆" 
 * @param bool $is_round 是否对小数进行四舍五入 
 * @param bool $is_extra_zero 是否对整数部分以0结尾，小数存在的数字附加0,比如1960.30， 
 *             有的系统要求输出"壹仟玖佰陆拾元零叁角"，实际上"壹仟玖佰陆拾元叁角"也是对的 
 * @return string
