Req #75062 [NEW]: Unload classes / reset php status

From: tomi dot po at koodia dot com Operating system: All PHP version: Next Major Version Package: Dynamic loading Bug Type: Feature/Change Request Bug description:Unload classes / reset php status Description: ------------ I am proposing a functions "unload_all_classes()", "unload_included_files()" or "reset_php()" Basically the idea is to reset the PHP back to the status when the program started, yet continue from the next line of code after the function call. Scenario: legacy system A, new system B, both systems need to run concurrently, it depends on condition C, which system need to be executed to handle the request. This condition C, is something that can be determined only inside the code. In this scenario I thought that maybe if I start the request and execute system B, but if it determines that this request is not intended for that, it'll simply fold - reset back to its status, and run legacy system A to handle the request. The point is to ease the migration pains. Further developement could return a "savepoint", so that you could get back to the original state. Something like this: "Savepoint function reset_php( Savepoint $savepoint = null )" "If savepoint is null, resets back to the original state (in which the php started) and returns the old state (savepoint). If savepoint is not null, and is legitimate savepoint it will reset the php status to this savepoint, and returns the old savepoint - otherwise returns FALSE. In either case the execution continues from the next line.
