如何在php中将所有键值合并为一个数组

Question

我有一个如下所示的数组值，

Array ( [0] => ["f","a","s","d"] [1] => ["d","b","a","c"] [2] => ["c"])

而且我还希望像下面提到的那样合并数组值

Array ( [0] => ["f","a","s","d","d","b","a","c","c"])

所有键值应合并到一个新的数组键下

在 PHP 5.6 版本中，您可以使用更好的方法来做到这一点。PHP 5.6 添加了称为 splat operator (...) 的新功能解包数组：

$arr = Array (["f","a","s","d"],["d","b","a","c"],["c"]);
$result = array_merge(...$arr);
