note 93889 added to pdo.query

The example here is not very good. Firstly, why has the author used print over echo? Secondly, showing users how to use this function using print_r() or var_dump() would give readers a better example of the kind of result to expect. My example looks like this: <?php $sql="SHOW TABLES FROM $_dbname"; $r=$db->query($sql)->fetchAll(); var_dump($r); ?> ---- Server IP: 87.124.86.46 Probable Submitter: 82.152.138.226 (proxied: 82.152.138.226) ---- Manual Page -- http://www.php.net/manual/en/pdo.query.php Edit -- https://master.php.net/note/edit/93889 Del: integrated -- https://master.php.net/note/delete/93889/integrated Del: useless -- https://master.php.net/note/delete/93889/useless Del: bad code -- https://master.php.net/note/delete/93889/bad+code Del: spam -- https://master.php.net/note/delete/93889/spam Del: non-english -- https://master.php.net/note/delete/93889/non-english Del: in docs -- https://master.php.net/note/delete/93889/in+docs Del: other reasons-- https://master.php.net/note/delete/93889 Reject -- https://master.php.net/note/reject/93889 Search -- https://master.php.net/manage/user-notes.php
