adding comma to a number?

[techlover]

Hi,

I am trying to figure out the best way to change something like this:

8294564547

into this:

8,294,564,547

I was thinking there had to be an easy and resource saving way to do this.

Thanks

have a look at the php manual and number_format()

thanks!

I was looking in my books but was not sure what type of function I was looking for.
