note 83153 added to language.oop5.abstract

While building my database class, I came across something I didn't see any documentation on... abstract class db { abstract protected function prepareSelect(); } class dbPlugin extends db { /** * Prepare Select * Populates $this->currentQuery with MySQL formatted SELECT query. * * @param string Fields to retrieve * @param string Table from which fields will be selected * @param string Optional WHERE restriction **/ protected function prepareSelect( $fields, $table, $where = NULL ) { $this->currentQuery .= "SELECT {$fields} FROM {$this->dbSettings['sqlPrefix']}{$table}"; if ( $where !== NULL ) { $this->currentQuery .= " WHERE {$where}"; } } } While executing the script I was greeted with: Fatal error: Declaration of dbPlugin::prepareSelect() must be compatible with that of db::prepareSelect() in [...]\includes\plugins\dbMySQL.php on line 209 The fix? Adding the same expected variables to the parent abstract method. abstract class db { abstract protected function prepareSelect( $fields, $table, $where ); } I am unsure as to whether this is common knowledge or not, but I figured I would share to ease someone else's frustration while figuring out what was going awry. :) ---- Server IP: 208.69.120.35 Probable Submitter: 74.70.179.203 ---- Manual Page -- http://www.php.net/manual/en/language.oop5.abstract.php Edit -- https://master.php.net/note/edit/83153 Del: integrated -- https://master.php.net/note/delete/83153/integrated Del: useless -- https://master.php.net/note/delete/83153/useless Del: bad code -- https://master.php.net/note/delete/83153/bad+code Del: spam -- https://master.php.net/note/delete/83153/spam Del: non-english -- https://master.php.net/note/delete/83153/non-english Del: in docs -- https://master.php.net/note/delete/83153/in+docs Del: other reasons-- https://master.php.net/note/delete/83153 Reject -- https://master.php.net/note/reject/83153 Search -- https://master.php.net/manage/user-notes.php
