note 53844 added to function.trim

here's a heads up folks. in the event that you want to check the result of a trim for being empty the following code fails:: $emptyvar = " "; if ( empty(trim($emptyvar)) ) { echo "It was empty"; } this code works as expected:: $emptyvar = " "; $check = trim($emptyvar); if ( empty($check) ) { echo "It was empty"; } ---- Manual Page -- http://www.php.net/manual/en/function.trim.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+53844 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+53844&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+53844&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+53844&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+53844&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+53844&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+53844&report=yes Search -- http://master.php.net/manage/user-notes.php
