Array_column, php version requires 5.5 +

$ Arr1 = Array ('title' => 'Happy traveling out',), Array ('title' => 'A Good Game ',)); $ arr2 = Array ('title' => 'youbi travel',), Array ('title' => 'kuaiyou ',)); var_dump (array_merge (array_column ($ arr1, 'title'), array_column ($ arr2, 'title'); array (4) {[0] => string (15) "Yueda travel" [1] => string (10) "A tour is good" [2] => string (12) "Youbi travel" [3] => string (12) ""}

Use the array_merge method

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

Assume that the preceding two 2D arrays are $ arr1 and $ arr2.
First, use the array_column () function to obtain the values of two-dimensional array columns (),
The values of the 'title' field in the two arrays are obtained in two anonymous index arrays.
Array_column ($ arr1, 'title ');
Then use the array_merge () array merging function to merge the two arrays:
$ New_arr = array_merge (array_column ($ arr1, 'title'), array_column ($ arr2, 'title '));
