Note that since unset() returns void, you can't do this: isset($some_var) && unset($some_var); You'll get: Parse error: syntax error, unexpected T_UNSET in ... The reason is because it would parse as <bool> && <void>; which is not a valid PHP statement. Thus, the only alternative is to actually use if statement. ---- Server IP: 208.69.120.35 Probable Submitter: 64.124.65.175 ---- Manual Page -- http://www.php.net/manual/en/function.unset.php Edit -- https://master.php.net/note/edit/78516 Del: integrated -- https://master.php.net/note/delete/78516/integrated Del: useless -- https://master.php.net/note/delete/78516/useless Del: bad code -- https://master.php.net/note/delete/78516/bad+code Del: spam -- https://master.php.net/note/delete/78516/spam Del: non-english -- https://master.php.net/note/delete/78516/non-english Del: in docs -- https://master.php.net/note/delete/78516/in+docs Del: other reasons-- https://master.php.net/note/delete/78516 Reject -- https://master.php.net/note/reject/78516 Search -- https://master.php.net/manage/user-notes.php
