note 96246 added to function.trim

There is a trap when making "form prefilters". Something like $_POST = array_map('trim', $_POST) may be not what we wanted, because when there are arrays in form made by field[] this "prefilter" return not an array but, according to his behavior, string. So as a effect we see in var_dump not array but field = "Array" what can mess up our validation. ---- Server IP: 194.24.174.37 Probable Submitter: 95.51.3.218 ---- Manual Page -- http://www.php.net/manual/en/function.trim.php Edit -- https://master.php.net/note/edit/96246 Del: integrated -- https://master.php.net/note/delete/96246/integrated Del: useless -- https://master.php.net/note/delete/96246/useless Del: bad code -- https://master.php.net/note/delete/96246/bad+code Del: spam -- https://master.php.net/note/delete/96246/spam Del: non-english -- https://master.php.net/note/delete/96246/non-english Del: in docs -- https://master.php.net/note/delete/96246/in+docs Del: other reasons-- https://master.php.net/note/delete/96246 Reject -- https://master.php.net/note/reject/96246 Search -- https://master.php.net/manage/user-notes.php
