I have an array-like:
Array
(
[0] => 4
[1] => 1861
)
Array
(
[0] => 4
[1] => 1938
)
Array
(
[0] => 4
[1] => 1452
)
Array
(
[0] => 4
[1] => 1938
)
Array
(
[0] => 21
)
This is a single array contain this array of elements. I need the result like :
$arr = array(4,1861,1938,1452,21);
That means I need the only array unique values from these arrays. For this, I am using array_walk_recursive(), array_merge() etc. But I didn't get my results.
Merge all the arrays and then call array_unique().
$result = array_unique(array_merge(...$array));
...$array spreads the elements of the original array into arguments to array_merge().
If you're using an old version of PHP before ellipsis, use call_user_func_array() instead.
$result = array_unique(call_user_func_array('array_merge', $array));
call_user_func_array('array_merge', $array) instead of using ellipsis.you need to use array_merge then array_unique
$array = array_unique (array_merge ($array1, $array2));
check this please https://stackoverflow.com/a/10572576/2429434
$array = array_unique (array_merge (...$array1)); check this stackoverflow.com/a/17041344/2429434
