PHP - number_format and rounding

Question

The number_format function in PHP seems to round by default. My understanding is that this function is useful for separating every three numbers with a comma. Like 1403423 becomes 1,404,423 when using number_format.

So, if I have a large number that I want rounded to two decimal places, how can I do this and still have the commas properly displayed?

Desired behavior: 12042.529 --> 12,042.53

If only one parameter is given, number will be formatted without decimals, but with a comma (",") between every group of thousands. If two parameters are given, number will be formatted with decimals decimals with a dot (".") in front, and a comma (",") between every group of thousands. — user557846
