php - Combine 2 arrays of different length -

i have array 100 values(array1). have array 8 values(array2). want take values array2 , use them keys , extract values in array1 keys.

the array_combine function won't work of different lengths.

i have tried

function array_combine2($arr1, $arr2) {     $count = min(count($arr1), count($arr2));     return array_combine(array_slice($arr1, 0, $count), array_slice($arr2, 0, $count)); } 

but doesn't work.....this gives me array correct keys, values incorrect, think because slicing array1.

could give assistance. there fair amount of literature on already, know, give solutions similar 1 above isn't working.

many time have taken.

something one:

function combine($array1, $array2) {     $array3 = array();     foreach ($array2 $key => $value) { //loop through entries of array2          //get entry of array1 corresponds value of array2's entry         if (isset($array1[$value]) {             $array3[$key] = $array1[$value]          }     }      return $array3; } 

i haven't tested should give thought.
