• How to “flatten” a multi-dimensional array to simple one in PHP? 21 answers

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);
