My second PHP question this week.... I'm writing a PHP app which includes things such as form validation and database interaction. So far, almost everything has been written procedurally. However, I started playing around with PHP's OO stuff, and it's cool. Problem is, this app is being submitted for a competition, and it's graded both on speed and how well I know the language. It would make me seem more 'knowledgeable' (I think) if I broke everything up into object, but on the other hand it requires more lines of code than doing it procedurally. So which should I go with? I hear that OO is slower (and thinking about it this makes sense), however I wanted verification.
