note 114037 added to function.require-once

I think it's important (at least for beginners) to mention somewhere clearly visible that require_once, when being used in a class, cannot be outside a function. (I am aware that even this, i.e. using it within the function is bad practice). However, that information could have saved me some valuable time troubleshooting the "unexpected T_REQUIRE_ONCE" error. ---- Server IP: 72.52.91.14 Probable Submitter: 72.52.91.14 ---- Manual Page -- http://php.net/manual/en/function.require-once.php Edit -- https://master.php.net/note/edit/114037 Del: integrated -- https://master.php.net/note/delete/114037/integrated Del: useless -- https://master.php.net/note/delete/114037/useless Del: bad code -- https://master.php.net/note/delete/114037/bad+code Del: spam -- https://master.php.net/note/delete/114037/spam Del: non-english -- https://master.php.net/note/delete/114037/non-english Del: in docs -- https://master.php.net/note/delete/114037/in+docs Del: other reasons-- https://master.php.net/note/delete/114037 Reject -- https://master.php.net/note/reject/114037 Search -- https://master.php.net/manage/user-notes.php
