PHP array_replace multidimensional array with one-dimensional array

July 1, 2022

I would like to merge my $semi array into the $full.

I get the $semi array back from my input field and want to merge it into $full to save it into my database.

I have these two arrays:

array = full
Array
(
    [Cars] => Array
        (
            [Volvo] => 0
            [Mercedes] => 0
            [BMW] => 0
            [Audi] => 0
        )

    [Motorcycle] => Array
        (
            [Ducati] => 0
            [Honda] => 0
            [Suzuki] => 0
            [KTM] => 0
        )
)

array = semi
Array
(
    [Volvo] => 1
    [Audi] => 1
)

I want the array to look like this:

Array
(
    [Cars] => Array
        (
            [Volvo] => 1
            [Mercedes] => 0
            [BMW] => 0
            [Audi] => 1
        )

    [Motorcycle] => Array
        (
            [Ducati] => 0
            [Honda] => 0
            [Suzuki] => 0
            [KTM] => 0
        )
)

already tried array_replace, array_replace.
tried $replaced = array_replace($full, $semi);

>Solution :

You should loop your $semi array and check if it exists in one of $full arrays, then add to it:

foreach ($semi as $semiItem => $semiValue) {
    foreach ($full as &$fullItems) {
        if (isset($fullItems[$semiItem])) {
            $fullItems[$semiItem] = $semiValue;
        }
    }
}
