How to merge one dimensional array and two dimensional array in php

Question

I have two array one is two dimensional and second is one dimensional and want to merge in a two dimensional array.

For Example :

# array1
Array
(
    [0] => Array
        (
            [id] => 598          
        )

    [1] => Array
        (
            [id] => 599        
        )
)
# array2
Array
(       
    [id] => 66    
)

#resultant array
Array
(
    [0] => Array
        (
            [id] => 598
        )
    [1] => Array
        (
            [id] => 599
        )
    [2] => Array
        (
            [id] => 66         
        )
)

In above example array1 and array2 are two input array and want to result as resultant array.

I have tried array_merge php function but it is not working.

How to do that?

If you just want to add an element it will work:

$array1[] = $array2;

If you want to create a new array it should work:

<?php
$array1 = [
    0 => ['id' => 598],
    1 => ['id' => 599],
];    
$result_array = $array1;    
$array2 = [
    'id' => 66,
];

$result_array[] = $array2;    
print_r($result_array);    
?>

In this case just add to new element in $array1 an $array2.

If you have more items in $array2 you can do it like follows:

$result_array = $array1; 
foreach ($array2 as $key => $value) {
    $result_array[] = [$key => $value];
}
print_r($result_array);

It is not working. `Array ( [0] => Array ( [0] => Array ( [id] => 598 ) [1] => Array ( [id] => 599 ) ) [1] => Array ( [id] => 66 ) )` – Vinaya Maheshwari Nov 28 '16 at 13:56
It does for me. Check for more info there: http://sandbox.onlinephpfunctions.com/code/e63fe6f45753cacd6c1040a731c7290e70162439 – Karol Gasienica Nov 28 '16 at 14:00
No I want to create a new `two dimensional` array. – Vinaya Maheshwari Nov 28 '16 at 14:01

But How to identify it is a `one dimensional` or `two dimensional`? Because these are dynamic. – Vinaya Maheshwari Nov 28 '16 at 14:04

you can just check which array has `$array[0]` set, like `isset($array[0])`. And you would know which one is numeric and according to your code which is two dimension – Karol Gasienica Nov 28 '16 at 14:10
Thanks, it is working. – Vinaya Maheshwari Nov 29 '16 at 04:15

You can get the value from array_value then assign the id key to your values and then merge your array.

$array1 = array(
    array('id' => "2"),
    array('id' => "3"),
);

$array2 = array(
    'id' => "1"
);

$array2['id'] = array_values($array2);

$data = array_merge($array2,$array1);

I can't do this, because I am getting array1, array2 and more like dynamically from database. – Vinaya Maheshwari Nov 28 '16 at 14:00
