note 129902 added to function.session-gc

Do not use: if (session_gc() == false) OR if (!session_gc()) to evaluate if the garbage collector was triggered successfully since it also returns how many sessions it deleted, which can be 0 (and that evaluates to false with loose operators). Sounds dumb, but it's a pitfall i fell into and it generated some confusion. Instead, use strict operator "===": if (session_gc() === false) ---- Server IP: 45.112.84.4 Probable Submitter: 80.90.5.137 (proxied: 2800:a4:7f7:bb00:8958:2f63:ddf4:55d5) ---- Manual Page -- https://php.net/manual/en/function.session-gc.php Edit -- https://main.php.net/note/edit/129902 Del: integrated -- https://main.php.net/note/delete/129902/integrated Del: useless -- https://main.php.net/note/delete/129902/useless Del: bad code -- https://main.php.net/note/delete/129902/bad+code Del: spam -- https://main.php.net/note/delete/129902/spam Del: non-english -- https://main.php.net/note/delete/129902/non-english Del: in docs -- https://main.php.net/note/delete/129902/in+docs Del: other reasons-- https://main.php.net/note/delete/129902 Reject -- https://main.php.net/note/reject/129902 Search -- https://main.php.net/manage/user-notes.php
