If both arrays always have the same length and there are not issues with the order in both arrays or keys existing in arrayItems and arrayValues it's simple:

$result = array();
foreach ($arrayItems as $key => $value) {
  $result[] = $arrayItems[$key] + $arrayValues[$key];
}

If you run into problems (values overwritten, etc.), please edit your question with specifics.

Edit: I fixed an important error in my answer it needs to be $result[].

There are a few small differences between my answer and another answer, and I feel like explaining them:

array() and [] are the same. They create an empty array.
foreach and for behave the same if the arrays are properly sorted and indexed. It's up to you what you prefer.
$result[] and array_push are very similar. One difference is that array_push requires an initialized array, while [] will create it if necessary. Another is that you can user more than 2 parameters for array_push.
the + operator and array_merge mainly differ, if there is a key in both arrays. + will keep the first one; merge the last. There a other subtle differences.

Edit 2 Or just use array_map as suggested in another answer. But I'm not deleting this wall of text.

+1 for standing up for your wall of text. :) But really, it is a very well explained answer. Just one suggestion - the unofficial site policy is to not label your edits with **Edit**, etc.. You can see what was changed easily enough in the edit history of the post.

You can map array_merge over the two arrays.

$result = array_map('array_merge', $arrayItems, $arrayValue);

$i = 0;
foreach($arrayItems as $arrayItem)
{
     array_push($arrayItem[$i]["isAlias"],$arrayValue[$i]["isAlias"]);
    $i++;
}

You can make use of array_merge() inside a for loop that merges both indexes:

$merge = [];
for ($i = 0; $i < count($arrayItems); $i++) {
  array_push($merge, array_merge($arrayItems[$i], $arrayValue[$i]));
}
var_dump($merge);

Which results in the following:

array (size=4)
  0 => 
    array (size=3)
      'item' => string 'firstname' (length=9)
      'value' => string 'John' (length=4)
      'isAlias' => string 'false' (length=5)
  1 => 
    array (size=3)
      'item' => string 'lastname' (length=8)
      'value' => string 'Doe' (length=3)
      'isAlias' => string 'false' (length=5)
  2 => 
    array (size=3)
      'item' => string 'adress' (length=6)
      'value' => string '3 garden street' (length=15)
      'offical' => string 'true' (length=4)
  3 => 
    array (size=3)
      'item' => string 'Tel' (length=3)
      'value' => string '123456' (length=6)
      'active' => string 'true' (length=4)

This can be seen working here.

Note that this assumes that order of both arrays will always be consistent.

Hope this helps! :)

reset($arrayItems);
reset($arrayValue);
foreach( $arrayValue as $value ){
 $aKey = key($value);
 //. no size limitation on arrays
 $arrayItems[key($arrayItems)][$aKey] = $value[$aKey];
 next($arrayItems);
}
print_r($arrayItems);
