用于检查PHP中的其他数组值的数组值？

Question

I have an array $minus

array(3) { [0]=> string(6) "people" 
           [1]=> string(7) "friends" 
           [2]=> string(8) "siblings" 
         }

And I have an array $user

array(3) { ["people"]=> string(3) "100" 
           ["friends"]=> string(2) "10" 
           ["siblings"]=> string(2) "57" 
         }

I can get the values of $user by using the values of $minus like,

echo $user[$minus[0]] . ', ' . $user[$minus[1]] . ', ' . $user[$minus[2]];
// Would echo: 100, 10, 57

But how can I get the values of $user by using the values of $minus into a new array, the new array should be like,

array(3) { [0]=> string(3) "100" 
           [1]=> string(2) "10" 
           [2]=> string(2) "57" 
         }

I have tried using foreach loops but can never get it right?

Answer 1

foreach($minus as $key=>$value) {
  $new_array[$key] = $user[$value];
}
