note 74685 added to features.persistent-connections

I'm just thinking about persistent mysql connections... Now I think of this "problem": My script uses different databases at the same connection. What would happen, if two users would call my script at nearly the same time? Person A starts and finishes an interaction with DB 1, changes to DB 2 and starts the first query to DB 2. At this moment person B starts the same script and uses DB 1. Will A's queries fail or will both script calls work independent despite the same mysql connection? ---- Server IP: 69.147.83.197 Probable Submitter: 91.17.192.88 ---- Manual Page -- http://www.php.net/manual/en/features.persistent-connections.php Edit -- https://master.php.net/note/edit/74685 Del: integrated -- https://master.php.net/note/delete/74685/integrated Del: useless -- https://master.php.net/note/delete/74685/useless Del: bad code -- https://master.php.net/note/delete/74685/bad+code Del: spam -- https://master.php.net/note/delete/74685/spam Del: non-english -- https://master.php.net/note/delete/74685/non-english Del: in docs -- https://master.php.net/note/delete/74685/in+docs Del: other reasons-- https://master.php.net/note/delete/74685 Reject -- https://master.php.net/note/reject/74685 Search -- https://master.php.net/manage/user-notes.php
