Поиск по словам в строке?

[new_forward]

Вот моя функция которая делает запрос и сортирует :

function GetList($fcv_array, $sortBy='', $ascending=true, $limit='')

	{
		$sqlLimit = ($limit != '' && $sortBy == ''?"LIMIT $limit":'');
		if (sizeof($fcv_array) > 0)
		{
			$questionList = Array();
			$Database = new DatabaseConnection();
			$this->pog_query = "select questionid from `question` where ";
			for ($i=0, $c=sizeof($fcv_array); $i<$c; $i++)
			{
				if (sizeof($fcv_array[$i]) == 1)
				{
					$this->pog_query .= " ".$fcv_array[$i][0]." ";
					continue;
				}
				else
				{
					if ($i > 0 && sizeof($fcv_array[$i-1]) != 1)
					{
						$this->pog_query .= " AND ";
					}
					if (isset($this->pog_attribute_type[$fcv_array[$i][0]]) && $this->pog_attribute_type[$fcv_array[$i][0]][0] != 'NUMERIC' && $this->pog_attribute_type[$fcv_array[$i][0]][0] != 'SET')
					{
						$this->pog_query .= "`".strtolower($fcv_array[$i][0])."` ".$fcv_array[$i][1]." '".($fcv_array[$i][2])."'";
					}
					else
					{
						$this->pog_query .= "`".strtolower($fcv_array[$i][0])."` ".$fcv_array[$i][1]." '".$fcv_array[$i][2]."'";
					}
				}
			}
			$this->pog_query .= " order by questionid DESC $sqlLimit";

			$Database->Query($this->pog_query);
			$thisObjectName = get_class($this);
			for ($i=0; $i < $Database->Rows(); $i++)
			{
				$question = new $thisObjectName();
				$question->Get($Database->Result($i, "questionid"));
				$questionList[] = $question;
			}

			if ($sortBy != '')
			{
				$f = '';
				$question = new question();
				if (isset($question->pog_attribute_type[$sortBy]) && ($question->pog_attribute_type[$sortBy][0] == "NUMERIC" || $question->pog_attribute_type[$sortBy][0] == "SET"))
				{
					$f = 'return $question1->'.$sortBy.' > $question2->'.$sortBy.';';
				}
				else if (isset($question->pog_attribute_type[$sortBy]))
				{
					$f = 'return strcmp(strtolower($question1->'.$sortBy.'), strtolower($question2->'.$sortBy.'));';
				}
				usort($questionList, create_function('$question1, $question2', $f));
				if (!$ascending)
				{
					$questionList = array_reverse($questionList);
				}
				if ($limit != '')
				{
					$limitParts = explode(',', $limit);
					if (sizeof($limitParts) > 1)
					{
						return array_slice($questionList, $limitParts[0], $limitParts[1]);
					}
					else
					{
						return array_slice($questionList, 0, $limit);
					}
				}
			}
			return $questionList;
		}
		return null;
	}

Подправить ее бы...
