note 80032 added to function.isset

Note: isset() only checks variables as anything else will result in a parse error. In other words, the following will not work: isset(trim($name)). isset() is the opposite of is_null($var) , except that no warning is generated when the variable is not set. ---- Server IP: 58.65.236.81 Probable Submitter: 123.202.148.251 ---- Manual Page -- http://www.php.net/manual/en/function.isset.php Edit -- https://master.php.net/note/edit/80032 Del: integrated -- https://master.php.net/note/delete/80032/integrated Del: useless -- https://master.php.net/note/delete/80032/useless Del: bad code -- https://master.php.net/note/delete/80032/bad+code Del: spam -- https://master.php.net/note/delete/80032/spam Del: non-english -- https://master.php.net/note/delete/80032/non-english Del: in docs -- https://master.php.net/note/delete/80032/in+docs Del: other reasons-- https://master.php.net/note/delete/80032 Reject -- https://master.php.net/note/reject/80032 Search -- https://master.php.net/manage/user-notes.php
