note 119317 added to function.mysql-affected-rows

I was just testing "INSERT INTO ... ON DUPLICATE KEY UPDATE" syntax, on PHP 5.3.29 and mysql_affected_rows() was returning either 2 for updated row, 1 for inserted new row, and also 0, which was not documented, evidently when nothing was inserted. I was inserting a single row. ---- Server IP: 72.52.91.14 Probable Submitter: 75.148.49.82 ---- Manual Page -- http://php.net/manual/en/function.mysql-affected-rows.php Edit -- https://master.php.net/note/edit/119317 Del: integrated -- https://master.php.net/note/delete/119317/integrated Del: useless -- https://master.php.net/note/delete/119317/useless Del: bad code -- https://master.php.net/note/delete/119317/bad+code Del: spam -- https://master.php.net/note/delete/119317/spam Del: non-english -- https://master.php.net/note/delete/119317/non-english Del: in docs -- https://master.php.net/note/delete/119317/in+docs Del: other reasons-- https://master.php.net/note/delete/119317 Reject -- https://master.php.net/note/reject/119317 Search -- https://master.php.net/manage/user-notes.php
