PHP RMB lowercase to uppercase function, unlimited length, accurate to cent (recommended)

This article introduces a PHP implementation of a small capitalization of the function, unlimited digital length, can be accurate to the points. If you need a friend, refer to it. When you print an invoice or display a bill, you often need to capitalize the RMB amount from lowercase. The following is an improved function of the small capitalization of the renminbi, the function is as follows: 1. Support astronomical, the whole number of the theory can be infinitely long; 2. Support decimal, for currency, generally accurate to decimal two digits, you can set whether the decimal place is rounded; 3. Support custom currency units, some systems require capital is "round", some requirements are "meta", can be customized; 4. Support integer 0 to end with a decimal number to customize the end of the "0", for example, some system requirements 1960.30 such a number to the capital is "a thousand and nine hundred Yuan three corner", and some systems require "a thousand and a nine hundred Yuan," the three corners ", these two cases according to the" correctly fill in the basic provisions "Are correct and can now be customized.
