在PHP开发中如何使用Google Spreadsheets进行数据管理和可视化

// 使用Google API访问Google Spreadsheets中的数据
require_once 'google-api-php-client/vendor/autoload.php';

$client = new Google_Client();
$client->setApplicationName('Google Sheets and PHP');
$client->setScopes(Google_Service_Sheets::SPREADSHEETS_READONLY);
$client->setAccessType('offline');
$client->setAuthConfig('credentials.json');

$service = new Google_Service_Sheets($client);
$spreadsheetId = 'SPREADSHEET_ID';
$range = 'Sheet1!A2:E';
$response = $service->spreadsheets_values->get($spreadsheetId, $range);
$values = $response->getValues();

// 计算每个学生的总分
$sums = array();
foreach ($values as $row) {
    $name = $row[0];
    $age = $row[1];
    $math = $row[2];
    $english = $row[3];
    $total = $math + $english;
    $sums[] = array('name' => $name, 'age' => $age, 'math' => $math, 'english' => $english, 'total' => $total);
}

// 使用Google Chart生成柱状图
$data = array();
foreach ($sums as $row) {
    $data[] = array($row['name'], $row['total']);
}

// 初始化Google Chart
echo '<div id="chart_div"></div>';
echo '<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>';
echo '<script type="text/javascript">';
echo 'google.charts.load('current', {'packages':['corechart']});';
echo 'google.charts.setOnLoadCallback(drawChart);';
echo 'function drawChart() {';
echo '  var data = google.visualization.arrayToDataTable('.json_encode(array(array('Name', 'Total'), $data)).');';
echo '  var options = {title: 'Student Scores', vAxis: {title: 'Total'}, hAxis: {title: 'Name'}};';
echo '  var chart = new google.visualization.ColumnChart(document.getElementById('chart_div'));';
echo '  chart.draw(data, options);';
echo '}';
echo '</script>';
