Join 2 array without using merge or foreach

Navigation

The problem is explained simply, I have two arrays: 

array(0,1,2,3,4);
array(5,6,7,8,9);

I need both arrays to make one only: 

array(0,1,2,3,4,5,6,7,8,9)

But I can not use foreach or while, since they are arrays that contain at least 100 records and that delays the response time, I would like to know if PHP has any native function that does it, something like this: 

unir_array(array,array);

I do not know, I always search in English on Google but until now I can not achieve it.

You can use array_merge () which combines the arrays you want, you just have to put them as parameters: 

$array3 = array_merge($array1, $array2);

Or join them by "concatenation" with the use of the + operator: 

$array3 = $array1 + $array2;

Check out the PHP documentation , where it's best explained, greetings.

It is the solution with better performance that occurred to me. 

$final = $array_a+array_combine(range(count($array_a),count($array_b)), $array_b);
