php使用array_chunk函数将一个数组分割成多个数组

$array = ['name' => 'tom', 'age' => 20, 3, 4, 5, 'a', 'b'];

$chunk_result = array_chunk($array, 3);

Array( [0] => Array  (   [0] => tom   [1] => 20   [2] => 3  ) [1] => Array  (   [0] => 4   [1] => 5   [2] => a  ) [2] => Array  (   [0] => b  ))

$chunk_result = array_chunk($array, 3, true);

Array( [0] => Array  (   [name] => tom   [age] => 20   [0] => 3  ) [1] => Array  (   [1] => 4   [2] => 5   [3] => a  ) [2] => Array  (   [4] => b  ))
