note 91596 added to pdostatement.fetch

From the official documentation, "The return value of this function on success depends on the fetch type. In all cases, FALSE is returned on failure.". This statement is incomplete. Actually, in all cases, FALSE is returned on failure or when no data found (at least for PHP 5.2.9). Run following code on your box to verify it (minor changes on the code may be needed): <?php $styles = array( PDO::FETCH_ASSOC, PDO::FETCH_BOTH, PDO::FETCH_BOUND, PDO::FETCH_CLASS, PDO::FETCH_INTO, PDO::FETCH_LAZY, PDO::FETCH_NUM, PDO::FETCH_OBJ, ); $dbh = new PDO('mysql:dbname=testdb;host=localhost', 'test', 'test'); $sth = $dbh->prepare("select * from application where false"); foreach ($styles as $style) { $sth->execute(); $result = $sth->fetch($style); echo $style, ': '; var_dump($result); } ?> ---- Server IP: 208.69.120.35 Probable Submitter: 208.67.191.194 ---- Manual Page -- http://www.php.net/manual/en/pdostatement.fetch.php Edit -- https://master.php.net/note/edit/91596 Del: integrated -- https://master.php.net/note/delete/91596/integrated Del: useless -- https://master.php.net/note/delete/91596/useless Del: bad code -- https://master.php.net/note/delete/91596/bad+code Del: spam -- https://master.php.net/note/delete/91596/spam Del: non-english -- https://master.php.net/note/delete/91596/non-english Del: in docs -- https://master.php.net/note/delete/91596/in+docs Del: other reasons-- https://master.php.net/note/delete/91596 Reject -- https://master.php.net/note/reject/91596 Search -- https://master.php.net/manage/user-notes.php
