How to sort a multi-dimensional array by the values ​​of another non-dimensional array?

Question

PHP

It is necessary that the second array be sorted by the values ​​of the second
. Another difficulty is that the second array can have more keys than the first, and they must go further in order
1 array

Array
(
    [1] => B SPB
    [2] => Z SPZ
    [3] => A SPA
    [4] => C SPC
)

2 array

Array
(
    [A SPA] => Array
        (
            [title] => A SPA
            [resources] => Array
                (
                    [208] => 208
                )
        )

    [B SPB] => Array
        (
            [title] => B SPB
            [resources] => Array
                (
                    [232] => 232
                )
        )

    [C SPC] => Array
        (
            [title] => C SPC
            [resources] => Array
                (
                    [257] => 257
                )
        )

    [HTD] => Array
        (
            [title] => HTD
            [resources] => Array
                (
                    [277] => 277
                )
        )
        
    [Z SPZ] => Array
        (
            [title] => Z SPZ
            [resources] => Array
                (
                    [188] => 188
                )
        )
)

Answer 1

You need to iterate over the first array, get the value from the second, add it to the resulting array, and unset this value in the second. After iterating through all the values ​​of the first array, merge the result (array_merge) with what is left in the second array

$resultArray = [];
foreach ($firstArray as $key) {
    if (isset($secondArray[$key])) {
        $resultArray[$key] = $secondArray[$key];
        unset($secondArray[$key]);
    }
}

$resultArray = array_merge($resultArray, $secondArray);
