note 115220 added to function.array-walk

There is a note about 3 years ago regarding using this for trimming. array_map() may be cleaner for this. I haven't checked the time/resource impact: $result = array_map("trim", $array); ---- Server IP: 72.52.91.14 Probable Submitter: 70.91.12.217 ---- Manual Page -- http://php.net/manual/en/function.array-walk.php Edit -- https://master.php.net/note/edit/115220 Del: integrated -- https://master.php.net/note/delete/115220/integrated Del: useless -- https://master.php.net/note/delete/115220/useless Del: bad code -- https://master.php.net/note/delete/115220/bad+code Del: spam -- https://master.php.net/note/delete/115220/spam Del: non-english -- https://master.php.net/note/delete/115220/non-english Del: in docs -- https://master.php.net/note/delete/115220/in+docs Del: other reasons-- https://master.php.net/note/delete/115220 Reject -- https://master.php.net/note/reject/115220 Search -- https://master.php.net/manage/user-notes.php
