• PHP: merge two arrays while keeping keys instead of reindexing? 5 answers

I have a multiple arrays which I'd like to put into a single array in order to sort it:

$weight = array($weight);
$dev = array_combine($missing, $weight);

echo "<pre>"; 
print_r($dev); 
echo "</pre>";

Output:

Array (
  [angular] => 2
) 
Array (
  [android sdk] => 3
) Array (
  [application] => 1
)

Now how do I turn the array above into this?

Array (
    [android sdk] => 3
    [angular] => 2
    [application] => 1 )

I've tried the below from a solution that I've found on this site, but it returns NULL:

$weight = array($weight);
$dev = array_combine($missing, $weight);
$result = call_user_func_array("array_merge", $dev);

echo "<pre>"; 
print_r($result); 
echo "</pre>";

EDIT

Here is my $missing array, some arrays are empty because a match hasn't been found against some keywords:

Array
(
)
Array
(
    [0] => angular
)
Array
(
    [0] => android sdk
)
Array
(
    [0] => application
)
Array
(
)

Here are the value from $weight:

3 2 3 1 3

How can I get this?

Array (
    [android sdk] => 3
    [angular] => 2
    [application] => 1 )

</div>

You can use array_merge function.

Therefore, the code will be

array_merge($array1, $array2);
