note 109163 added to function.session-start

@will dot joi at hotmail dot com In your example, there is no difference between simple and double quote : if($_SESSION['nome'] == "") is the same as ($_SESSION['nome'] == '') You could use if(strlen($_SESSION['nome'])) But if you want to check session you must prefer : if(isset($_SESSION['nome'])) or the better way if(!empty($_SESSION['nome'])) The first test can be empty, not the second one. ---- Server IP: 69.147.83.197 Probable Submitter: 90.24.204.11 ---- Manual Page -- http://www.php.net/manual/en/function.session-start.php Edit -- https://master.php.net/note/edit/109163 Del: integrated -- https://master.php.net/note/delete/109163/integrated Del: useless -- https://master.php.net/note/delete/109163/useless Del: bad code -- https://master.php.net/note/delete/109163/bad+code Del: spam -- https://master.php.net/note/delete/109163/spam Del: non-english -- https://master.php.net/note/delete/109163/non-english Del: in docs -- https://master.php.net/note/delete/109163/in+docs Del: other reasons-- https://master.php.net/note/delete/109163 Reject -- https://master.php.net/note/reject/109163 Search -- https://master.php.net/manage/user-notes.php
