Question

我想分塊大數。例如。

33 thousand like this  33.000 
33 milion like this 33.000.000 

我該如何在PHP中做到這一點？

Answer 1

使用number_format()：

number_format(
    $number, 
    0,   //amount of decimal points 
    ',',  //decimal seperator 
    '.'  //thousands seperator 
);

下面是一個例子：

number_format("33000",0,"","."); 
number_format("33000000",0,"",".");
