I've got 2 quick quesitons on php.
1) I'm guessing php has regex functionallity, how do I do a replace in php? (ie replace all occurances of a "," with a space)
2) How do I make sure a number is in decimal format to 1/100ths? (ie 99.5 changes to 99.50, and 45.67312 changes to 45.67) and how do you round in php?
