我有这段代码:
$i=0;
$start_date = date("Y/m/d");
$end_date = date('Y/m/d', strtotime($start_date . " -7 days"));
while($days7=mysql_fetch_assoc($q)):
$next_date = strtotime($i--." days", strtotime($start_date));
$date = date("Y/m/d",$next_date);
#Let's get the latest click combined from the latest 7 days
$combined7=mysql_query("SELECT sum(value) FROM `xeon_stats_clicks` WHERE user='".$userdata['username']."' AND typ='4' AND data='$date' ORDER BY data DESC LIMIT 8") or die(mysql_error());
print mysql_num_rows($combined7);
endwhile;
我需要看看有多少行$combined7
。目前,我正在使用print mysql_num_rows($combined7);
,但只是打印出来:1 1 1 1 1(每行的数字“1”)
如何计算总数?
(PS $i 必须设置为 0)
