再沒有重複的記錄創建兩個給定陣列新數組

Question

Array1 
(
    [0] => Array 
     (
      [idapartment] => 212 
      [guests] => 3 
     ) 

    [1] => Array 
     (
      [idapartment] => 1889 
      [guests] => 6 

     ) 

) 

Array2 
(
    [0] => Array 
     (
      [id] => 212 
      [guests] => 3 

     ) 

    [1] => Array 
     (
      [id] => 1549 
      [guests] => 3 

     ) 

    [2] => Array 
     (
      [id] => 727 
      [guests] => 3 

     ) 

    [3] => Array 
     (
      [id] => 1889 
      [guests] => 3 

     ) 

    [4] => Array 
     (
      [id] => 1927 
      [guests] => 3 

     ) 

) 

想要第三個這樣的ARRAY3 ::即刪除IDS 212,1889記錄

Array3 
(
    [0] => Array 
     (
      [id] => 1927 
      [guests] => 3 

     ) 

    [1] => Array 
     (
      [id] => 1549 
      [guests] => 6 

     ) 

    [2] => Array 
     (
      [id] => 727 
      [guests] => 6 

     ) 

) 

Answer 1

foreach($array2 as $child2){ 
    $count = count($array1); 
    $i = 0; 
    for($i = 0; $i < $count ; $i++){ 
     if($array[$i]['idapartment'] == $child['id']) 
      unset($array1[$i]);  // removes ids 212,1889 records 
    } 
} 

$array3 = array_merge($array1, $array2);
