【PHP】配列から一つのカラムを取り出す、及びキー名をカラム名にする

<?php
$rows = [
    0 => [ 'id' => 10, 'language' => 'PHP',        'ｆramework' => 'Laravel'],
    1 => [ 'id' => 20, 'language' => 'Java',       'ｆramework' => 'Spring'],
    2 => [ 'id' => 30, 'language' => 'JavaScript', 'ｆramework' => 'Vue.js' ],
    3 => [ 'id' => 40, 'language' => 'Ruby',       'ｆramework' => 'Ruby on Rails' ]
];
$abc = array_column($rows, 'language', 'id');

var_dump($abc);

?>

もしくは

<?php

$array = [
    0 => [ 'id' => 10, 'language' => 'PHP',        'ｆramework' => 'Laravel'],
    1 => [ 'id' => 20, 'language' => 'Java',       'ｆramework' => 'Spring'],
    2 => [ 'id' => 30, 'language' => 'JavaScript', 'ｆramework' => 'Vue.js' ],
    3 => [ 'id' => 40, 'language' => 'Ruby',       'ｆramework' => 'Ruby on Rails' ]
];


foreach($array as $list){
    $data[$list['id']] = $list;
    unset($data[$list['id']]['id']);
}

var_dump($data);
?>

#出力結果

array(4) {
  [10]=>
  string(3) "PHP"
  [20]=>
  string(4) "Java"
  [30]=>
  string(10) "JavaScript"
  [40]=>
  string(4) "Ruby"
}
