Search with values in a array object

Question

I have an array like this. What I am trying to do is remove duplicate entries. I want to compare values of array with different keys.

For example, the first 2 elements in array has key areacode. 3 & 4 has key state. I want to compare the values of areacode and state and remove the duplicate entries. That is, 0 and 2 have state/areacode =>'US', so I want to remove one of these.

How should I do it?

Array (
  [0] => stdClass Object
    (
        [areacode] => US
        [id] => 7-CxFsXZBGGCiYlW-NYKFw
        [city] => San Francisco
    )

  [1] => stdClass Object
    (   
        [areacode] => CL
        [id] => 7-CxFsXZBGGCiYlW-NYKFw
        [city] => San Francisco
    )

  [2]=>stdClass Object
    (    
        [state] => US
        [id] => 7-CxFsXZBGGCiYlW-NYKFw
        [city] => San Francisco
    )
  [3]=>stdClass Object
    (    
        [state] => SA
        [id] => 7-CxFsXZBGGCiYlW-NYKFw
        [city] => San Francisco
    )
)

use array_filter

$filtered = array_filter($your_array, function($obj){
  $obj_array = (array)$obj;
  return $obj_array['state'] != 'US';
});
