PHP：如何配对一个欠费的值

数组就像

array ( 
      [0] => a
      [1] => b
      [2] => c
      [3] => d
      [4] => e
      [5] => f
      [6] => g
      [7] => h
     )

我想把它们像……一样配对

Array 
( [0] => Array ( 
    [0] => a
    [1] => b)

  [1] => Array ( 
    [0] => c
    [1] => d) 

  [2] => Array ( 
    [0] => e
    [1] => f)

  [3] => Array ( 
    [0] => g
    [1] => h)
)

我该怎么做？有8个值，我想从这8个值中得到4对。我是php新手，所以我对php不太了解，我搜索了谷歌，但找不到解决方案。

您可以使用：

print_r(array_chunk($arr, 2));
