How do I list the time array together?

Array results after the database has been printed:

Array(    [0] => Array        (            [department] => 雅典娜              [sign] => 0            [time] => 2015年06月01日            [surname] => 星史        )    [1] => Array        (            [department] => 雅典娜            [sign] => 0            [time] => 2015年06月02日            [surname] =>  星史        )    [2] => Array        (            [department] => 雅典娜            [sign] => 0            [time] => 2015年06月03日            [surname] => 瞬        )    [3] => Array        (            [department] => 雅典娜            [sign] => 0            [time] => 2015年06月03日            [surname] => 紫龙        )

I want to count the same array, for example, there are two arrays of star history, statistics are 2, others are 1.
Then the array notation is

$array=array();foreach($上面打印的数组 as $v){    if(!isset($array[$v['surname']])){              $out_put[$v['surname']]['time']=$v['time'];              $array[$v['surname']]['count']=1;    }else{         $array[$v['surname']]['count']=$array[$v['surname']]['count']+1;    }}

And then print out

Array(    [星史] => Array        (           //问题再这里，如何数组输出多个时间呢  [time] = 2015年06月01日、2015年06月02日             [time] =2015年06月01日;            [count] => 2        )    [瞬] => Array        (             [time] =2015年06月03日;             [count] => 1        )    [紫龙 => Array        (           [time] =2015年06月03日;            [count] => 1        ))

How does this print output time?
