PHP开发技巧：如何实现数据分析图表和报表功能

<?php
// 引入Highcharts库文件
require_once 'path_to_highcharts/highcharts.php';

// 数据库连接配置
$host = 'localhost';
$user = 'root';
$pass = 'password';
$db   = 'database';
$conn = mysqli_connect($host, $user, $pass, $db);

// 查询数据
$query = "SELECT date, value FROM data_table";
$result = mysqli_query($conn, $query);

// 处理数据
$data = array();
while ($row = mysqli_fetch_assoc($result)) {
    $date = strtotime($row['date']);
    $value = intval($row['value']);
    $data[] = array($date * 1000, $value);
}

// 实例化Highcharts对象
$chart = new Highcharts();

// 配置图表属性
$chart->chart->renderTo = 'container';
$chart->title->text = '数据折线图';
$chart->xAxis->type = 'datetime';
$chart->yAxis->title->text = '数值';
$chart->series[] = array('name' => '数据', 'data' => $data);

// 输出图表
$chart->printChart();
?>

<?php
// 引入PHPExcel库文件
require_once 'path_to_phpexcel/phpexcel.php';

// 创建对象
$objPHPExcel = new PHPExcel();

// 设置属性
$objPHPExcel->getProperties()->setCreator('Your Name')
                             ->setLastModifiedBy('Your Name')
                             ->setTitle('报表')
                             ->setSubject('报表')
                             ->setDescription('报表')
                             ->setKeywords('报表')
                             ->setCategory('报表');

// 获取数据
$query = "SELECT * FROM data_table";
$result = mysqli_query($conn, $query);

// 写入数据
$row = 1;
while ($data = mysqli_fetch_assoc($result)) {
    $objPHPExcel->getActiveSheet()->setCellValue('A'.$row, $data['column1']);
    $objPHPExcel->getActiveSheet()->setCellValue('B'.$row, $data['column2']);
    // ...
    $row++;
}

// 保存为Excel文件
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save('report.xlsx');
?>
