Dollarfy Function those the following things to a floating point number:
This function inserts a comma separator into every 3 digits. For example: 100000.1252 will be 100,000.1252.
Round to the decimal number to the next significant figure. For example: 100,000.1252 will be 100,000.13
Add a dollar sign to the number. For example: 100,000.13 will be $100,000.13
Syntax: dollarfy (Decimal Number, Decimal places);
Example: dollarfy (100000.1252, 2);
Output will be: $100,000.13 (Rounded to the second Decimal place)
Note: You will need the commify function for it to work. dollarfy() function needs the commify() function to work.

Reiventing the Wheel. Instead of reiventing the wheel, you could just use the number_format() function builtin to PHP since version 3:

...or money_format(), http://ca.php.net/manual/en/function.money-format.php and you don't even need to add the dollar by yourself.
