PHP - 使用另一个数组排序数组

Question

Is there an easy way to sort an array with a variable array made for this task? For example:

$fruits [
   'Apple' => '12',
   'Cherry' => '10',
   'Lemon' => '34', 
   'Peach' => '6'
]

$order [
   1 => 'Peach',
   2 => 'Other',
   3 => 'Lemon',
   4 => 'Other2',
   5 => 'Apple',
   6 => 'Cherry',
   7 => 'Other3'
]

I'd like to return this kind of array:

$ordered_fruits [
   'Peach' => '6',
   'Lemon' => '34',
   'Apple' => '12',
   'Cherry' => '10'
]

Answer 1

$ordered_fruits = array();
foreach($order as $value) {

   if(array_key_exists($value,$fruits)) {
      $ordered_fruits[$value] = $fruits[$value];
   }
}
