php怎么生成表格数据类型

<?php
// 假设这是从数据库或其他来源获取的数据
$data = [
    ['Name' => 'Alice', 'Age' => 24, 'City' => 'New York'],
    ['Name' => 'Bob', 'Age' => 27, 'City' => 'Los Angeles'],
    ['Name' => 'Charlie', 'Age' => 22, 'City' => 'Chicago']
];

echo '<table border="1">';
echo '<tr><th>Name</th><th>Age</th><th>City</th></tr>';

foreach ($data as $row) {
    echo '<tr>';
    foreach ($row as $cell) {
        echo '<td>' . htmlspecialchars($cell) . '</td>';
    }
    echo '</tr>';
}

echo '</table>';
?>

<?php
// 假设这是从数据库或其他来源获取的数据
$data = [
    ['Name' => 'Alice', 'Age' => 24, 'City' => 'New York'],
    ['Name' => 'Bob', 'Age' => 27, 'City' => 'Los Angeles'],
    ['Name' => 'Charlie', 'Age' => 22, 'City' => 'Chicago']
];

// 设置HTTP头，告诉浏览器这是一个CSV文件
header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename="data.csv"');

$fp = fopen('php://output', 'w');

foreach ($data as $row) {
    fputcsv($fp, $row);
}

fclose($fp);
?>
