PHP framework - There are multiple arrays of the same level in the PHP array and I want to merge them into one array

The printed result is multiple arrays of the same level. This is the first time I saw it and I want to merge it into one large array for easy operation

<code>

array_column, php version requires 5.5+

<code class="php">
$arr1 = Array
(
    Array
        (
            'title' => '悦动行出游',
        ),

     Array
        (
            'title' => 'A游不错',
        ));
  $arr2= Array
(
    Array
        (
            'title' => '悠比旅行',
        ),

     Array
        (
            'title' => '快快旅行',
        ));
        var_dump(array_merge(array_column($arr1,'title'),array_column($arr2,'title')));
    array(4) {
  [0]=>
  string(15) "悦动行出游"
  [1]=>
  string(10) "A游不错"
  [2]=>
  string(12) "悠比旅行"
  [3]=>
  string(12) "快快旅行"
}    
        </code>

Use array_merge method

<code>array_map(function($v){ 
    return $v['title'];
    }, $arr);</code>

Suppose your two two-dimensional arrays above are $arr1 and $arr2.
First use the function array_column() to obtain the column value of a two-dimensional array.
Get the value of the 'title' field in the two arrays into two anonymous index arrays respectively.
array_column($arr1, 'title');
Then use the array_merge() array merge function to merge the two arrays:
$new_arr = array_merge(array_column($arr1, 'title'), array_column($arr2, 'title' ));
