note 127210 added to migration80.incompatible

If you want to "demote" the "Undefined array key" error back from a WARNING to a NOTICE, you can do it this way: //Convert the error from E_WARNING to E_USER_NOTICE. set_error_handler(function($errno, $error){ if (!str_starts_with($error, 'Undefined array key')){ return false; //default error handling rules. }else{ trigger_error($error, E_USER_NOTICE); return true; } }, E_WARNING); //You may also then want to ignore E_USER_NOTICE. ini_set ("error_reporting", E_ALL & ~E_NOTICE & ~E_USER_NOTICE); ---- Server IP: 45.112.84.4 Probable Submitter: 45.91.157.133 (proxied: 185.254.136.122) ---- Manual Page -- https://php.net/manual/en/migration80.incompatible.php Edit -- https://main.php.net/note/edit/127210 Del: integrated -- https://main.php.net/note/delete/127210/integrated Del: useless -- https://main.php.net/note/delete/127210/useless Del: bad code -- https://main.php.net/note/delete/127210/bad+code Del: spam -- https://main.php.net/note/delete/127210/spam Del: non-english -- https://main.php.net/note/delete/127210/non-english Del: in docs -- https://main.php.net/note/delete/127210/in+docs Del: other reasons-- https://main.php.net/note/delete/127210 Reject -- https://main.php.net/note/reject/127210 Search -- https://main.php.net/manage/user-notes.php
