[php]Unexpected $this po foreach Opcje

[NickOver]

Cześć,
Mam błąd którego istnienia za bardzo nie rozumiem. Oto kod:

[PHP] pobierz, plaintext 
public function remove($table = NULL, $parameters = NULL){
			$this->setTable($table);
			if($parameters === NULL){
				$this->displayError('You must specific parameters to use this method');
				exit();
			}
			if (is_array($parameters)){
				$whereString = null;
				foreach ($parameters as $field => $value){
					if (empty($whereString)){
						$whereString = " WHERE ".$field." = '".$value."'";
					} else {
						$whereString.= " AND ".$field." = '".$value."'";
					}
				}
				$this->_query = $this->_connection->prepare("DELETE FROM "$this->_table.$whereString);
			} else {
				$this->_query = $this->_connection->prepare("DELETE FROM "$this->_table.$paraqmeters);
			}
			return $this->_query;
		}
[PHP] pobierz, plaintext 

Php wywala mi "Unexpected $this ..." przy "$this->_query = $this->_connection->prepare". Wiecie może czemu?
