在php中一组三个分组大数字

Question

I want to chunk large numbers. For example.

//between each three decimals a dot should be placed
33 thousand like this       33.000
33 milion   like this   33.000.000

How can I do this in php?

Answer 1

Use number_format():

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