note 95067 added to function.preg-replace-callback

tijn's currying example is very nice, but, like any use of create_function(), it leaves behind tons of occupied memory, because it creates an anonymous function for every variation of parameters. And since there's no "destroy_function()" which would allow us to reclaim that memory, given enough calls you may end up maxing out the PHP memory limit. So be very careful if you use that technique across large amounts of iterations. ---- Server IP: 69.147.83.197 Probable Submitter: 194.88.148.6 ---- Manual Page -- http://www.php.net/manual/en/function.preg-replace-callback.php Edit -- https://master.php.net/note/edit/95067 Del: integrated -- https://master.php.net/note/delete/95067/integrated Del: useless -- https://master.php.net/note/delete/95067/useless Del: bad code -- https://master.php.net/note/delete/95067/bad+code Del: spam -- https://master.php.net/note/delete/95067/spam Del: non-english -- https://master.php.net/note/delete/95067/non-english Del: in docs -- https://master.php.net/note/delete/95067/in+docs Del: other reasons-- https://master.php.net/note/delete/95067 Reject -- https://master.php.net/note/reject/95067 Search -- https://master.php.net/manage/user-notes.php
