PHP: How To Format Numbers

In PHP there is an easy way to format numbers with decimal separators and thousands separators an so on. A number like 123456.789 can be easily formated to something like 123,456.79 or 123.456,79. In this article I’ll show you how.

But how about 9348394309.238? 😉 In this case, it will be very useful to add some thousands separators. Because then it will look like this: 9,348,394,309.238. And maybe we want to limit the decimals to two. So it will look like this: 9,348,394,309.24 (please note the rounded decimal). So this makes it way more readable.
