Merging two array elements into one array element in PHP - php

Question

I want to merge two arrays into one array as follows,
Array1:
Array
(
[0] => Array
(
[id] => 3
[sku] => KOG456
[cart_id] => 2
[name] => Young Money
[slug] => young-money
[route_id] => 47
[description] =>
This is test song
[excerpt] =>
[saleprice] => 90.00
[related_products] =>
[images] => {"1c6b0883fc94c5f644497ec488cdf8cb":{"filename":"1c6b0883fc94c5f644497ec488cdf8cb.jpg","alt":"Test","caption":"","primary":true}}
[seo_title] =>
[meta] =>
[enabled] => 1
)
)
Array2:
Array
(
[0] => Array

[filename] => Beethovens_Symphony_No._9_(Scherzo).wma
[title] => Young Money

Expected array result is:
Array

[id] => 3
[sku] => KOG456
[cart_id] => 2
[name] => Young Money
[slug] => young-money
[route_id] => 47
[description] =>

[meta] =>
[enabled] => 1
[filename] => Beethovens_Symphony_No._9_(Scherzo).wma

How to merge these array elements into one array element ?

Answer 1

foreach ($origArray as $key => &$subArray)
$subArray += $arrayToBeAdded[$key];
Where $origArray is your array which is to be merged into and $arrayToBeAdded the array you merge into.

Answer 2

User array_merge_recursive():
$final = array_merge_recursive($array1, $array2);

Answer 3

Try this little known overload of the + operator for arrays:
$result = $array1[0] + $array2[0]

Answer 4

Use function array_merge($array1[0], $array2[0]) . Following is the example for the same
$array1 = array(0=>array('1'=>1,'2'=>2,'3'=>3));
$array2 = array(0=>array('4'=>4,'5'=>5,'6'=>6));
$result[0] = array_merge($array1[0],$array2[0]);
echo '<pre>';
print_r($result);

Answer 5

Since you have unique keys, you could use something as simple as the + operator (union)...
For example:
$arr1 = [1=>'testing',2=>'stack',3=>'overflow'];
$arr2 = [4=>'something',5=>'else',6=>'here'];
$arr3 = $arr1 + $arr2;
print_r($arr3);
Results:
Array ( [1] => testing [2] => stack [3] => overflow [4] => something [5] => else [6] => here )

Answer 6

For this php has multiple functions. You can use $arrays = array_combine($array1, $array2);.
PHP.net - array_combine
Hope it helped!
