[phpesp-dev] Purpose to this code?

[Erek D. <er...@nb...>]

Hi All,
	this is a snippet from survey_results.inc:
	Line 406:
                $sql = "SELECT C.content FROM question_choice C
                        WHERE C.question_id='${qid}' AND C.content NOT 
			LIKE '!other%'
                        ORDER BY C.id";
                if ($result = mysql_query($sql)) {
                    for ($j = 0; $j < mysql_num_rows($result); $j++)
                        $counts[mysql_result($result, $j, 0)] = null;
                    mysql_free_result($result);
                }

	The only thing that I see this does is enumerates through the $counts array and resets everything to null,
would it be better to change this to one line: $counts = array();
	I have done this in my developement copy with no ill effects.
Any of you know another purpose to this block?
