php - 如何将这些数组组合成一个多维数组

Question

假设我有这些数组：

$group1= array('id' => '1','title' => 'Group 1','description' => 'This is group1');
$group2= array('id' => '2','title' => 'Group 2','description' => 'This is group2');
$group3= array('id' => '3','title' => 'Group 3','description' => 'This is group3');

如何将它们组合成一个多维数组，如下所示：

$groups=array(array('id' => '1','title' => 'Group 1','description' => 'This is group1'),array('id' => '2','title' => 'Group 2','description' => 'This is group2'),array('id' => '3','title' => 'Group 3','description' => 'This is group3'))

我试过使用 array_map 但它没有产生我需要的数组。谢谢。

Answer 1

你在找$groups = array($group1, $group2, $group3);吗？

Answer 2

$new_arr = array($group1,$group2,$group3);

Answer 3

$groups[] = array_merge ($group1,$group1,$group1);
