note 53737 added to function.isset

Just a note on the previous users comments. isset() should only be used for testing if the variable exists and not if the variable containes an empty "" string. empty() is designed for that. Also, as noted previosuly !empty() is the best method for testing for set non-empty variables. ---- Manual Page -- http://www.php.net/manual/en/function.isset.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+53737 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+53737&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+53737&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+53737&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+53737&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+53737&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+53737&report=yes Search -- http://master.php.net/manage/user-notes.php
