Question

i had an associative array like this : i need to merge two array and last hr rating i need to add hrrating1 = , hr rating 2 = like this
array (
0 =>
array (
'skill_name' => 'JDK (Java Development Kit)',
'desc' => '',
'req_rating' => '2',
'user_rating' => '3',
'hrRating' => '2',
),
1 =>
array (
'skill_name' => 'Java Servlets',
'desc' => '',
'req_rating' => '4',
'user_rating' => '3',
'hrRating' => '3',
),
2 =>
array (
'skill_name' => 'JDK (Java Development Kit)',
'desc' => '',
'req_rating' => '2',
'user_rating' => '3',
'hrRating' => '2',
),
3 =>
array (
'skill_name' => 'Java Servlets',

'req_rating' => '4',
'user_rating' => '3',
'hrRating' => '4',
),
)
Needed Output :
array (
0 =>
array (
'skillName' => 'JDK',
'comments' => '',
'jobRating' => '2',
'userRating' => '3',
'skillGap' => '-1',
'hrRating1' => '7',
'hrRating2' => '2',
),
1 =>
array (
'skillName' => 'Java Servlets',
'comments' =>'',
'jobRating' =>'4',

'skillGap' => '1',
'hrRating1' => '2',
'hrRating2' => '3',
),
)
i need to combine both array with last column hrRating should different like hrRating1 & hrrating# like this any help regarding????

Answer 1

Updated (single array input)
I do not know if I can use skill_name as a array key (probably not), hence $tmp_skill, $tmp_index.
function process_collection($data) {
$tmp_skill = [];
$tmp_index = [];
$result = [];
foreach ($data as $k => $item) {
$skill = $item['skill_name'];
echo $skill.'<br>';
$idx = array_search($skill, $tmp_skill);
if ($idx === false) {
//$result[$idx]['_ratings'] = $item['hrRating'];
//continue;
$idx = count($tmp_skill);
$tmp_index[] = $idx;
$tmp_skill[] = $skill;
$result[$idx] = $item;
$result[$idx]['_ratings'] = [];
}
$result[$idx]['_ratings'][] = $item['hrRating'];
}
// conversion array of ratings to individual values 'hrRating1', 'hrRating2', ...
foreach($result as &$item) {
$i = 0;
foreach( $item['_ratings'] as $rate)
$item['hrRating' . (++$i)] = $rate;
unset($item['_ratings']);
unset($item['hrRating']);
}
return $result;
}

Answer 2

$array_2 = max($arra_1,$arra) ;
print_r($array_2);
Array ( [0] => Array ( [skillName] => JDK [comments] => [jobRating] => 2 [userRating] => 3 [skillGap] => -1 [hrRating] => 2 ) [1] => Array ( [skillName] => Java Servlets [comments] => [jobRating] => 4 [userRating] => 3 [skillGap] => 1 [hrRating] => 3 ) )

Answer 3

You can use the array_merge() merge function to combine arrays as following:
$comined_array=array_merge($array1,$array2);
Now the $combined_array will be containing the value of both $array1 and $array2.

Answer 4

What you are looking for is array merge. The function array combine is an array of keys and then values whereas array merge append arrays onto the first.
As mentioned in the other answers, change the array variables to match your own.
$array_1 = ['a'];
$array_2 = ['b'];
$new_array = array_merge($array_1, $array_2);
print_r($new_array);
// ['a', 'b']

Answer 5

You can try any from these alternatives:-
Assuming that both the array's has same elements and keys and named it as $arr1 and $arr2
Alternative 1 :- Make an array of all hrRating and asign it to main array
foreach ($arr1 as $key => $data) {
$arr1[$key]['hrRating'] = array($data['hrRating'], $arr2[$key]['hrRating']);
}
print_r($arr1);
Output :-
Array
(
[0] => Array
(
[skillName] => JDK
[comments] =>
[jobRating] => 2
[userRating] => 3
[skillGap] => -1
[hrRating] => Array
(
[0] => 2
[1] => 7
)
)
[1] => Array
(
[skillName] => Java Servlets
[comments] =>
[jobRating] => 4
[userRating] => 3
[skillGap] => 1
[hrRating] => Array
(
[0] => 3
[1] => 2
)
)
)
Alternative 2 :- Assign every hrRating values from different array with new sequence key
foreach ($arr1 as $key => $data) {
unset($arr1[$key]['hrRating']);
$arr1[$key]['hrRating1'] = $data['hrRating'];
$arr1[$key]['hrRating2'] = $arr2[$key]['hrRating'];
}
print_r($arr1);
Output :-
Array
(
[0] => Array
(
[skillName] => JDK
[comments] =>
[jobRating] => 2
[userRating] => 3
[skillGap] => -1
[hrRating1] => 2
[hrRating2] => 7
)
[1] => Array
(
[skillName] => Java Servlets
[comments] =>
[jobRating] => 4
[userRating] => 3
[skillGap] => 1
[hrRating1] => 3
[hrRating2] => 2
)
)

Answer 6

Just to add to the variety: Here is another way of re-arranging your array. I took the liberty of combining all arrays into a single master array $in. By doing a sequence of foreach calls will get your result fairly quickly.
I also added the feature that I named the individual rating arrays after their skill_name. If you don't like that, just comment out the line below:
// $j=$aa['skillName'];unset($aa['skillName']);
Here is the input data I used for testing:
$in=array(
array (
array (
'skillName' => 'JDK',
'comments' => '',
'jobRating' => '2',
'userRating' => '3',
'skillGap' => '-1',
'hrRating' => '2',
), array (
'skillName' => 'Java Servlets',
'comments' =>'',
'jobRating' =>'4',
'userRating' =>'3',
'skillGap' => '1',
'hrRating' => '3',
),
),
array (
array (
'skillName' => 'JDK',
'comments' => '',
'jobRating' => '2',
'userRating' => '3',
'skillGap' => '-1',
'hrRating' => '7',
), array (
'skillName' => 'Java Servlets',
'comments' =>'',
'jobRating' =>'4',
'userRating' =>'3',
'skillGap' => '1',
'hrRating' => '2',
)
),
array (
array (
'skillName' => 'JDK',
'comments' => 'not bad',
'jobRating' => '3',
'userRating' => '3',
'skillGap' => '-1',
'hrRating' => '4',
), array (
'skillName' => 'Java Servlets',
'comments' =>'',
'jobRating' =>'8',
'userRating' =>'3',
'skillGap' => '1',
'hrRating' => '1',
),
));
And this is the complete code for re-arranging:
foreach ($in as $i => $na) foreach($na as $j => $aa) {
$j=$aa['skillName'];unset($aa['skillName']);
foreach ($aa as $k => $v) $ret[$j][$k][]=$v;
}
print_r($ret);
And this is what I get as output:
Array
(
[JDK] => Array
(
[comments] => Array
(
[0] =>
[1] =>
[2] => not bad
)
[jobRating] => Array
(
[0] => 2
[1] => 2
[2] => 3
)
[userRating] => Array
(
[0] => 3
[1] => 3
[2] => 3
)
[skillGap] => Array
(
[0] => -1
[1] => -1
[2] => -1
)
[hrRating] => Array
(
[0] => 2
[1] => 7
[2] => 4
)
)
[Java Servlets] => Array
(
[comments] => Array
(
[0] =>
[1] =>
[2] =>
)
[jobRating] => Array
(
[0] => 4
[1] => 4
[2] => 8
)
[userRating] => Array
(
[0] => 3
[1] => 3
[2] => 3
)
[skillGap] => Array
(
[0] => 1
[1] => 1
[2] => 1
)
[hrRating] => Array
(
[0] => 3
[1] => 2
[2] => 1
)
)
)

Answer 7

you can combine arrays in two ways:
$third_array = combine_array($array1,$array2);
and the other way is:
$array = $array1 + $array2;
change the $array1 & $array2 as per your array names.
