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

you can use below code

function array_combine2($arr1, $arr2) {
    foreach($arr2 as $val){
     $arr3[] = $arr1[$val];
     }

    return $arr3;
}

For inctanse,

    $arr1['x'] = 2;
$arr1['y'] = 3;
$arr1['z'] = 4;

$arr2[0] = 'x';
$arr2[1] = 'y';
$arr2[2] = 'z';

the above function will return the below as resbonse

$arr3[0] = 2;
$arr3[1] = 3;
$arr3[2] = 4;
