如何將這些陣列成一個多維數組

Question

假如我有這些陣列：

$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'); 

如何將它們組合成一個多維數組是這樣的：

$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')) 

我一直在使用array_map嘗試，但它是不生產我需要的陣列。謝謝。

Answer 1

您是在查找$groups = array($group1, $group2, $group3);？

Answer 2

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

Answer 3

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