Category:Core -> Optimize
This page will keep track of all Regex improvements. Once the code improvement has been added, it will be marked as Added. If you get a chance, go through as many approvements as possible and approve it or don’t approve it. Keep in mind CodeIgniter’s goals (meaning don’t write improvements that won’t work everywhere). If a code improvement gets a lot of “Not Approved”, it will probably be dropped from this page.
DO NOT EDIT SUBMITTED CODE. IF YOU THINK OF A BETTER IMPROVEMENT, MARK THE CURRENT CODE AS “NOT APPROVED” AND SUBMIT YOUR OWN.
