Combine 2 arrays of different length

Question

I have an array with 100 values(array1). I have another array with 8 values(array2). I want to take the values from array2 and use them as keys and extract the values in array1

Answer 1

something like this one:

function combine($array1, $array2) {
    $array3 = array();
    foreach ($array2 as $key => $value) { //loop through all entries of array2

        //get the entry of array1 that corresponds to the value of array2's entry
        if (isset($array1[$value]) {
            $array3[$key] = $array1[$value] 
        }
    }

    return $array3;
}

I haven't tested it but it should give you something for thought.
