如何提高执行效率

<br />
for($i=0; $i<count($r); $i++)<br />
	{<br />
		$var = explode(" ,",$r[$i]);<br />
		$barcode = $var[0];<br />
		$num = $var[1];<br />
		$sql = "insert into `".$t."`(barcode,num) values('".$barcode."','".$num."')";<br />
		echo $sql.'<br />';<br />
		mysql_query($sql);<br />
	}<br />


一共有6000多条记录,如果每条记录都执行insert into,消耗时间很长,超过默认的90s。有无方法提高执行效率?
