note 124798 added to pdostatement.fetch

A prior poster indicated that this function returns a NULL when there are no results. This is not true. This function returns an empty array. fetchAll() returns the same. Also, the documentation specifies what happens on "failure", but doesn't indicate what constitutes a "failure". A "failure" could be where the function returns no results; that is, the query "failed". However, a "failure" is apparently a situation where the PDO error functions would reveal a "failure", as in illegal SQL syntax, or a query on a table which doesn't exist, etc. An empty result is not a "failure". Maybe that's obvious to everyone else, but it wasn't to me. ---- Server IP: 45.112.84.4 Probable Submitter: 38.142.137.34 (proxied: 2603:9000:d715:8900:5ca2:1160:6846:e26f) ---- Manual Page -- http://php.net/manual/en/pdostatement.fetch.php Edit -- https://master.php.net/note/edit/124798 Del: integrated -- https://master.php.net/note/delete/124798/integrated Del: useless -- https://master.php.net/note/delete/124798/useless Del: bad code -- https://master.php.net/note/delete/124798/bad+code Del: spam -- https://master.php.net/note/delete/124798/spam Del: non-english -- https://master.php.net/note/delete/124798/non-english Del: in docs -- https://master.php.net/note/delete/124798/in+docs Del: other reasons-- https://master.php.net/note/delete/124798 Reject -- https://master.php.net/note/reject/124798 Search -- https://master.php.net/manage/user-notes.php
