多维数组我怎么会拿一个数组像这样：

Array ([key1] => item1 [key2] => item2 [key3] => item3 [key4] => item4 [key5] => item5 [key6] => item6) 

PHP：

$array = array('key1' => 'item1','key2' => 'item2', 'key3' => 'item3','key4' => 'item4', 'key5' => 'item5','key6' => 'item6'); 

，并创建每3个值的多维数组的数组，如：

Array ([0] => Array ([0] => item1 [1] => item2 [2] => item3) [1] => Array ([0] => item4 [1] => item5 [2] => item6)) 

PHP：

$array = array(array('item1','item2','item3'), 
       array('item4','item5','item6')); 

所以，我可以输出不同的项目，如：$newArray[0][1]

Answer 1

array_chunk() - 斯普利特的数组分成块

$array = array('key1' => 'item1','key2' => 'item2', 'key3' => 'item3','key4' => 'item4', 'key5' => 'item5','key6' => 'item6'); 
$a2 = array_chunk($array, 3); 
echo $a2[0][1]; 

Answer 2

 
$new = array(); 
$vals = array_values($array); 
for ($i = 0; $i < count($array); $i += 3) { 
$new[] = array_slice($vals, $i, 3); 
}
