PHP:如何配对arrey值

Question

数组就像......

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

我想要他们喜欢..

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)
)

我怎样才能做到这一点？有8个值,我希望从这8个值中有4对.我是php的新手,所以我真的不知道php和我搜索谷歌,但无法找到解决方案.

Answer 1

你可以使用array_chunk():

print_r(array_chunk($arr, 2));
