我有这个while循环:
<?php
$q=mysql_query("SELECT * FROM xeon_stats_clicks WHERE user='".$userdata['username']."' AND typ='4' ORDER BY data DESC LIMIT 8") or die(mysql_error());
while($clickData=mysql_fetch_assoc($q)):
$r=mysql_query("SELECT sum(value) FROM `xeon_stats_clicks` WHERE user='".$userdata['username']."' AND typ='3' AND data='".date("Y/m/d")."' ORDER BY data DESC LIMIT 8");
echo mysql_result($r, 0);
endwhile;
?>
这只会给我今天的值行的总和。我怎样才能获得过去 7 天的数据?
