时间戳是10位的,取的是当前时间戳:
$nowtime = strtotime(date('Y-m-d H:i:s')); //当前时间戳
得到的 $nowtime 有时候是 1393834011,有时候是 1393834062
我想实现一功能,怎么样能让时间戳取整变成这样的:1393834020,1393834070?
不能直接这么写:strtotime(date('Y-m-d H:i'));


回复讨论(解决方案)

   $time=time();
 $time=$time/10;
 $time_zhengshu=floor($time);
 $time_zhengshu=$time_zhengshu*10;
 echo "$time_zhengshu";
 ?> 不知道这是不是你想要的 测试都是尾数为0.

echo round(1393834011 + 9, -1); //1393834020
echo round(1393834062 + 9, -1); //1393834070

float round ( float $val [, int $precision ] )

返回将 val 根据指定精度 precision(十进制小数点后数字的数目)进行四舍五入的结果。precision 也可以是负数或零(默认值)。 

楼上+1

   $time=time();
 $time=$time/10;
 $time_zhengshu=floor($time);
 $time_zhengshu=$time_zhengshu*10;
 echo "$time_zhengshu";
 ?> 不知道这是不是你想要的 测试都是尾数为0. 没看到楼主的需求,以为只是取整。徐版主的答案正确!

floor($time / 10) * 10
