考虑:

[name] => Array ( [1] => name#1
                  [2] => name#2
                  [3] => name#3
                  [4] => name#4
                  [5] =>
                  [6] =>
                  [7] =>
                  [8] =>
                  [9] =>
                )


$name = $_POST['name']

我想要结果4.

count ($name) = 9
count (isset($name)) = 1
count (!empty($name)) = 1

我认为最后一个会完成我需要的东西,但它不是(空条目来自表单上未填充的输入).
