count - 计算while循环内的数组总数

Question

计算数组。

数组 ( [0] => 4 [id] => 4 [1] => 2019-2020 [fyear] => 2019-2020 [2] => 01-04-2019 [start_date] => 01-04-2019 [3] => 31-03-2020 [end_date] => 31-03-2020 ) 数组 ([0] => 5 [id] => 5 [1] => 2020-2021 [fyear] => 2020- 2021 [2] => 01-04-2020 [开始日期] => 01-04-2020 [3] => 31-03-2021 [结束日期] => 31-03-2021 )

打印数组的总数，即
1。我们有 2 个数组。
2. 我想在循环内打印计数 2。
