PHP - Multidimensional array merge to one array

Question

I have 2 arrays like this:

Array One:

[
    [
        "id" => 1234
        "name" => "John"
    ],
    [
        "id" => 1235
        "name" => "doe"
    ]
]

Array Two:

[
    [
        "age" => 12
    ],
    [
        "age" => 13
    ]
]

I have tried it using and combine array_reduce, array_map or array_merge_recursive, but it still doesn't match the results.

How can I make the two arrays like below?

[
    [
        "id" => 1234
        "name" => "John"
        "age" => 12
    ],
    [
        "id" => 1235
        "name" => "doe"
        "age" => 13
    ]
]

Please help me. thank you

Answer 1

array-map with combination of array-merge should do the trick:

$c = array_map('array_merge', $a, $b);

Answer 2

You could iterate the first array and merge with second array with respected index match

$merged =[];
foreach($a as $k => $val){
    array_push($merged,array_merge($val,$b[$k]));
}
print_r($merged);

You can use array_merge like :

<?php

$array = array(
                  ["id" => "1",  
                   "name" => "denba"
                 ],

                    ["id" => "1",  
                   "name" => "chpa7"
                 ],

              );              

$ages = array(
                  ["age" => "15",  

                 ],

                    ["age" => "17", 
                 ],

              );

foreach($array as $key => $value){
    $array[$key]=array_merge($array[$key], $ages[$key]);
}


var_dump($array); 
/*output:
    array(2) {
  [0]=>
  array(3) {
    ["id"]=>
    string(1) "1"
    ["name"]=>
    string(5) "denba"
    ["age"]=>
    string(2) "15"
  }
  [1]=>
  array(3) {
    ["id"]=>
    string(1) "1"
    ["name"]=>
    string(5) "chpa7"
    ["age"]=>
    string(2) "17"
  }
}
