I wasn't quite statisfied with the fact that SLOCcount didn't count css
Here's the revised estimate for Virtual Pet Rock including PHP
Totals grouped by language (dominant language first):
objc: 2001 (59.41%)
php: 1144 (33.97%)
css: 195 (5.79%)
Total Physical Source Lines of Code (SLOC) = 3,368
Development Effort Estimate, Person-Years (Person-Months) = 0.72 (8.59)
(Basic COCOMO model, Person-Months = 2.4 * (KSLOC**1.05))
Schedule Estimate, Years (Months) = 0.47 (5.66)
(Basic COCOMO model, Months = 2.5 * (person-months**0.38))
Estimated Average Number of Developers (Effort/Schedule) = 1.52
Total Estimated Cost to Develop = $ 96,690
(average salary = $56,286/year, overhead = 2.40).
Data generated using David A. Wheeler's 'SLOCCount'.
As you can see we are now rapidly approching an estimated devlopment cost of 100,000 dollars. To be fair: I don't make even close to $56,000 a year, despite the fact that the dollar is worth about as much as a pebble these days :)
To celebrate I have created a new Useless Statistics
category on this site and I will retroactively modfiy all relevant posts to go into this category.
