note 98781 added to function.isset

A little errata for my last comment. On the first line: "Keep that an empty string" = "Keep in mind that an empty string" And for the last snippet, the correct would be as follow: <?php (isset($a) && $a === ''); // => TRUE ?> Note the use of the "identical" operator (===) instead of "equal" (==) Sorry for the bother. It would be really appreciated if the wrong note could be edited and this errata removed. ---- Server IP: 69.147.83.197 Probable Submitter: 189.26.239.156 ---- Manual Page -- http://www.php.net/manual/en/function.isset.php Edit -- https://master.php.net/note/edit/98781 Del: integrated -- https://master.php.net/note/delete/98781/integrated Del: useless -- https://master.php.net/note/delete/98781/useless Del: bad code -- https://master.php.net/note/delete/98781/bad+code Del: spam -- https://master.php.net/note/delete/98781/spam Del: non-english -- https://master.php.net/note/delete/98781/non-english Del: in docs -- https://master.php.net/note/delete/98781/in+docs Del: other reasons-- https://master.php.net/note/delete/98781 Reject -- https://master.php.net/note/reject/98781 Search -- https://master.php.net/manage/user-notes.php
