note 97929 added to function.trim

While inserting data from web forms to databases, trimming the posted values to remove the spaces from the left and right sides can be a good idea to avoid the user faults. This code have to be located before the DB operations. <?php /* Stripping whitespaces from left and right sides of all posted data. * Put this before working with posted data. * */ // Remove whitespaces from left and right sides. function removeSpaces($str) { $newStr = trim($str); return $newStr; } // If any data posted to the page, send them for trimming. if ($_POST) { foreach ($_POST as $var => $value) { $value=removeSpaces($value); $_POST[$var] = $value; } } ?> ---- Server IP: 160.75.100.7 Probable Submitter: 217.131.110.221 ---- Manual Page -- http://www.php.net/manual/en/function.trim.php Edit -- https://master.php.net/note/edit/97929 Del: integrated -- https://master.php.net/note/delete/97929/integrated Del: useless -- https://master.php.net/note/delete/97929/useless Del: bad code -- https://master.php.net/note/delete/97929/bad+code Del: spam -- https://master.php.net/note/delete/97929/spam Del: non-english -- https://master.php.net/note/delete/97929/non-english Del: in docs -- https://master.php.net/note/delete/97929/in+docs Del: other reasons-- https://master.php.net/note/delete/97929 Reject -- https://master.php.net/note/reject/97929 Search -- https://master.php.net/manage/user-notes.php
