Php – How to put each element of array into another array in same order

I have first array:

Array
(
    [0] => generala value 1
    [1] => specificatii value 1
)

and second array is:

   Array
(
    [0] => Array
        (
            [title] => generala title 1
            [atribute_cat_id] => 1
            [product_id] => 98
        )

    [1] => Array
        (
            [title] => specificatii title 1
            [atribute_cat_id] => 2
            [product_id] => 98
        )    
)

I want to get this array form:

Array
(
    [0] => Array
        (
            [title] => generala title 1
            [atribute_cat_id] => 1
            [product_id] => 98
            [value] => generala value 1
        )

    [1] => Array
        (
            [title] => specificatii title 1
            [atribute_cat_id] => 2
            [product_id] => 98
            [value] => specificatii value 1
        )

)

I tried with array_merge but this method put all elements from first array to each element from second array!
Every time both arrays have same number of elements!
Any ideea?
Thank you!

    Like below you can do

    $firstArray = array(
    'generala' => 'generala value 1',
    'specificatii' => 'specificatii value 1',
);

$secondArray = array(
    array(
        'title' => 'generala title 1',
        'atribute_cat_id' => 1,
        'product_id' => 98,
    ),
    array(
        'title' => 'specificatii title 1',
        'atribute_cat_id' => 2,
        'product_id' => 98,
    ),
);

$resultArray = array();

foreach ($secondArray as $item) {
    $resultItem = $item;
    foreach ($firstArray as $key => $value) {
        if (is_string($key) && strpos($item['title'], $key) !== false) {
            $resultItem['value'] = $value;
            break;
        }
    }
    $resultArray[] = $resultItem;
}

echo '<pre>';
print_r($resultArray);

    A simple iterative loop is probably the easiest to follow. However, if you’re looking for something more compact then this might suit:

    $result = $secondArray;
array_walk(
    $result,
    fn(&$v, $k) => $v['value'] = $firstArray[$k]
);

    Loop over one of the arrays, using the indexes to access the corresponding element in the other array.

    foreach ($first_array AS $i => $value) {
    $second_array[$i]['value'] = $value;
}

    You can do this using a foreach loop. Keep it simple. 🙂

    $firstArray = [
    'generala value 1',
    'specificatii value 1',
];

$secondArray = [
    [
        'title' => 'generala title 1',
        'atribute_cat_id' => 1,
        'product_id' => 98,
    ],
    [
        'title' => 'specificatii title 1',
        'atribute_cat_id' => 2,
        'product_id' => 98,
    ],
];

// Create a copy
$result_array = array_values($secondArray);
foreach ($firstArray as $idx => $value) {
    $result_array[$idx]['value'] = $value;
}

    If you prefer the destructive approach:

    // Modify the array IN-PLACE
foreach ($firstArray as $idx => $value) {
    $secondArray[$idx]['value'] = $value;
}
