忙しい人向け Q. PDO::FETCH_ASSOCでフェッチするとき,キーを整数連番じゃなくてidにする方法は? A. PDO::FETCH_UNIQUEを組み合わせる. $sql = "SELECT id, * FROM people WHERE gender = 'female'"; $rows = $pdo->query($sql)->fetchAll(PDO::FETCH_ASSOC|PDO::FETCH_UNIQUE); var_dump($rows); /* [ 3 => ['id' => '3', 'name' => 'Lucy', 'gender' => 'female'], 5 => ['id' => '5', 'name' => 'Mary', 'gender' => 'female'], ] */
