【PHP】多次元配列の重複削除

Last updated at Posted at 2015-01-29

こういうデータがあったとして

[
  [
    "pit",
    "28"
    "id011"
  ],
  [
    "john",
    "34",
    "id023"
  ],
  [
    "bob",
    "24",
    "id011"
  ],
  [
    "marry",
    "23",
    "id032"
  ]
]

例えば「同じIDだったら除外したい」という場合とかに

 $tmp = array();
 $array_result = array();

 foreach( $array_org as $key => $value ){

  // 配列に値が見つからなければ$tmpに格納
  if( !in_array( $value['id'], $tmp ) ) {
   $tmp[] = $value['id'];
   $array_result[] = $value;
  }

 }
 $data = $array_result;
