How do I automatically add commas to numbers?

Greetings,

I have numbers stored in my MySQL database that look like this:
5234552346234

How can I get PHP to display that number as this?:
5,234,552,346,234

Thanks

 

Use PHP's number_format() function.

 

Number format will only work for the thousands separator.

 

PHP manual says
If only one parameter is given, number will be formatted without decimals, but with a comma (",") between every group of thousands.
The following code gives the exact output that peppy is looking for.

echo number_format('5234552346234');

I was going to suggest the php forum but it looks like you have the answer above
