PHPにおけるSQLクエリの結果を配列として取得する
行ごとに読み取りながら各従業員を出力せずに、 何らかの配列に記録することができます:
<?php
$row1 = mysqli_fetch_assoc($res);
$data[] = $row1;
$row2 = mysqli_fetch_assoc($res);
$data[] = $row2;
$row3 = mysqli_fetch_assoc($res);
$data[] = $row3;
$row4 = mysqli_fetch_assoc($res);
$data[] = $row4;
$row5 = mysqli_fetch_assoc($res);
$data[] = $row5;
$row6 = mysqli_fetch_assoc($res);
$data[] = $row6;
?>
結果として、変数 $data には
次のような2次元配列が格納されます:
<?php
[
['id' => 1, 'name' => 'user1', 'age' => 23, 'salary' => 400],
['id' => 2, 'name' => 'user2', 'age' => 25, 'salary' => 500],
['id' => 3, 'name' => 'user3', 'age' => 23, 'salary' => 500],
['id' => 4, 'name' => 'user4', 'age' => 30, 'salary' => 900],
['id' => 5, 'name' => 'user5', 'age' => 27, 'salary' => 500],
['id' => 6, 'name' => 'user6', 'age' => 28, 'salary' => 900],
]
?>
