I would like to sum up several arrays. I have a script that dynamically creates arrays without name. Below is an example. In my script i have a 90+ arrays. I want to sum up all it. All keys in that arrays be user id, so i only want sum values of keys. How to do it? Regards

Array 
( 
[1] => 1 
[2] => 1 
[3] => 1 
) 
Array 
( 
[1] => 1 
[2] => 1 
) 
Array 
( 
[1] => 1 
)

I want to get only one array result like:

Array

Add all your arrays into one array.

$all_arrays[] =Array 
( 
[1] => 1 ,
[2] => 1, 
[3] => 1 
); 

$all_arrays[] = Array 
( 
[1] => 1, 
[2] => 1 
) ;

$all_arrays[] = Array 
( 
[1] => 1 
);

 $results = [];
foreach($all_arrays as $arr)
 foreach($arr as $user_id=>$value)
 if(in_array($user_id,$results))
 $results[$user_id] = $results[$user_id] + $value;
 else
 $results[$user_id] = $value;

You would need to specify all arrays in the array_merge:

$result = array_count_values(array_keys(array_merge($array1, $array2, $array3)));

If you can get the arrays dynamically added to another $main_array like:

Array
(
 [0] => Array
 (
 [1] => 1
 [2] => 1
 [3] => 1
 )

 [1] => Array
 (
 [1] => 1
 [2] => 1
 )

 [2] => Array
 (
 [1] => 1
 )

)

Then it would be much easier:

$result = array_count_values(array_keys(array_merge(...$main_array)));
