cd /path/to/wiki chmod a+w config" ); } require_once( "install-utils.inc" ); require_once( "maintenance/updaters.inc" ); class ConfigData { function getEncoded( $data ) { # removing latin1 support, no need... return $data; } function getSitename() { return $this->getEncoded( $this->Sitename ); } function getSysopName() { return $this->getEncoded( $this->SysopName ); } function getSysopPass() { return $this->getEncoded( $this->SysopPass ); } } ?>
