php - 如何在PHP中更新数组？

Question

我想更新以下数组:

$old_array = array('c' => array( "a" => "1", "b" => "2"))

通过向其中添加以下数组:

$new_array = array('cc' => array( "a" => "1", "b" => "2"))

我的预期输出是:

$update_array = array('c' => array( "a" => "1", "b" => "2"), 'cc' => array( "a" => "1", "b" => "2"))

我将如何实现这一目标？任何帮助表示赞赏。

Answer 1

您需要使用函数 array_merge()

合并数组

有关该函数的更多信息here .

$old_array = array('c' => array( "a" => "1", "b" => "2")); 
$new_array = array('cc' => array( "a" => "1", "b" => "2"));

// merge arrays
$merged_array = array_merge($old_array, $new_array);
