php如何合并一维数组为二维数组

array array_chunk(array $array, int $size, bool $preserve_keys = false)

$array = array('cat', 'dog', 'fish', 'bird', 'hamster', 'rabbit'); $result = array_chunk($array, 2); print_r($result);

$array = array('cat', 'dog', 'fish', 'bird', 'hamster', 'rabbit'); $result = array_chunk($array, 2); $new_array = array(); foreach ($result as $res) { $new_array[] = $res; } print_r($new_array);

$array = array('cat', 'dog', 'fish', 'bird', 'hamster', 'rabbit'); $new_array = array(); for ($i = 0; $i < count($array); $i += 2) { $new_array[] = array($array[$i], $array[$i + 1]); } print_r($new_array);

Array ( [0] => Array ( [0] => cat [1] => dog ) [1] => Array ( [0] => fish [1] => bird ) [2] => Array ( [0] => hamster [1] => rabbit ) )
