Answer 1

$num = count($results);
foreach($results as $key=>$result){
print("['");
print($result['time']);
print("',");
print("71.72");
print(",");
print($result['total']);
print(",");
print($result['per']);
print(",'");
print("null");
print("'],\n");
if(（$key+1）==$num) echo "这是最后一条";
}

Answer 2

$result == $results[count($results)-1] ;

$results[count($results)-1] 是最后一条记录

Answer 3

看当前键是不是等于数组最后的一个就可以了
