删除键后将键移向 0

Question

所以我有一个数组：

Array ( [Favorite-Search-Engines] => Array ( 
[0] => Google 
[1] => Yahoo 
[2] => Bing 
[3] => DuckDuckGo ) )

我希望用户能够删除密钥，但如果他们删除了一个：

Array ( 
[Favorite-Search-Engines] => Array ( 
[0] => Google
[2] => Bing 
[3] => DuckDuckGo ) )

我希望键像这样向下移动到 0:

数组（ [Favorite-Search-Engines] => 数组 ( [0] => Google [1] => Bing [2] => DuckDuckGo ) )

有什么办法吗？提前致谢

Answer 1

最简单的方法是使用：

$re_indexed_array = array_values($your_modified_array);

Moving keys towards 0 after they are removed
