PHP phpspreadsheet 导出大数据 csv excel

PHP phpspreadsheet 导出大数据

1、composer 安装 phpspreadsheet 这个

composer require phpoffice/phpspreadsheet

2、composer 安装 phpspreadsheet 这个
普通的Excel根据内存来算 可能不超过4000条

普通的导出xlsx （亲测封顶3000多条）

set_time_limit(0);
for($i;$i<=60000;$i++){ // 这样6万条的话 可能
    $data[] = [
        'id' => $i+1,
        'name' => '用户'.($i+1)
    ];
}

$title = [
    [
        '编号', '用户'
    ],
];
$arrData = array_merge($title, $arrData);
$spreadsheet = new \PhpOffice\PhpSpreadsheet\Spreadsheet();

// 设置单元格格式 可以省略
$styleArray = [
    'font' => [
        'bold' => true,
        'size' => 14,
    ],
];
$spreadsheet->getActiveSheet()->getStyle('A1:B1')->applyFromArray($styleArray);
$spreadsheet->getActiveSheet()->getColumnDimension('A')->setWidth(25);
$spreadsheet->getActiveSheet()->getColumnDimension('B')->setWidth(25);
$spreadsheet->getActiveSheet()->fromArray($arrData);
$writer = new \PhpOffice\PhpSpreadsheet\Writer\Xlsx($spreadsheet);
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');//告诉浏览器输出07Excel文件
// header('Content-Type:application/vnd.ms-excel');//告诉浏览器将要输出Excel03版本文件
header('Content-Disposition: attachment;filename=test.xlsx');//告诉浏览器输出浏览器名称
header('Cache-Control: max-age=0');//禁止缓存
$writer->save('php://output');

优化后的导出xlsx （亲测封顶6万条）

如果加上优化的话 最多极限是6万条，这个是excel的文件限制
原理：其实主要是导出的时候服务器内存的问题导致无法导出大数据，所以要分流导出 并且释放内存 刷新缓冲

set_time_limit(0);
for($i;$i<=60000;$i++){
    $arrData[] = [
        'id' => $i+1,
        'name' => '用户'.($i+1)
    ];
}

$title = [
    [
        '编号', '用户'
    ],
];
$arrData = array_merge($title, $arrData);
$spreadsheet = new \PhpOffice\PhpSpreadsheet\Spreadsheet();

// 设置单元格格式 可以省略
$styleArray = [
    'font' => [
        'bold' => true,
        'size' => 14,
    ],
];
$spreadsheet->getActiveSheet()->getStyle('A1:B1')->applyFromArray($styleArray);
$spreadsheet->getActiveSheet()->getColumnDimension('A')->setWidth(25);
$spreadsheet->getActiveSheet()->getColumnDimension('B')->setWidth(25);
$spreadsheet->getActiveSheet()->fromArray($arrData);
$writer = new \PhpOffice\PhpSpreadsheet\Writer\Xlsx($spreadsheet);
header('Content-Description: File Transfer');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename=test.xlsx');
header('Cache-Control: max-age=0');
$writer->save('php://output');
$fp = fopen('php://output', 'a');//打开output流
mb_convert_variables('GBK', 'UTF-8', $columns);
fputcsv($fp, $columns);//将数据格式化为xlsx格式并写入到output流中

$dataNum = count( $arrData );
$perSize = 1000;//每次导出的条数
$pages = ceil($dataNum / $perSize);

for ($i = 1; $i <= $pages; $i++) {
    foreach ($arrData as $item) {
        mb_convert_variables('GBK', 'UTF-8', $item);
        fputcsv($fp, $item);
    }
    //刷新输出缓冲到浏览器
    ob_flush();
    flush();//必须同时使用 ob_flush() 和flush() 函数来刷新输出缓冲。
}
fclose($fp);
exit();

如果使用csv的话可以导出百万级，当然也要内存支持，但是也差不多足够

set_time_limit(0);
for($i;$i<=60000;$i++){
    $arrData[] = [
        'id' => $i+1,
        'name' => '用户'.($i+1)
    ];
}

$title = [
    [
        '编号', '用户'
    ],
];
$arrData = array_merge($title, $arrData);
$spreadsheet = new \PhpOffice\PhpSpreadsheet\Spreadsheet();

// 设置单元格格式 可以省略
$styleArray = [
    'font' => [
        'bold' => true,
        'size' => 14,
    ],
];
$spreadsheet->getActiveSheet()->getStyle('A1:B1')->applyFromArray($styleArray);
$spreadsheet->getActiveSheet()->getColumnDimension('A')->setWidth(25);
$spreadsheet->getActiveSheet()->getColumnDimension('B')->setWidth(25);
$spreadsheet->getActiveSheet()->fromArray($arrData);
$writer = new \PhpOffice\PhpSpreadsheet\Writer\Csv($spreadsheet);
header('Content-Description: File Transfer');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename=test.csv');
header('Cache-Control: max-age=0');
$writer->save('php://output');
$fp = fopen('php://output', 'a');//打开output流
mb_convert_variables('GBK', 'UTF-8', $columns);
fputcsv($fp, $columns);//将数据格式化为csv格式并写入到output流中

$dataNum = count( $arrData );
$perSize = 1000;//每次导出的条数
$pages = ceil($dataNum / $perSize);

for ($i = 1; $i <= $pages; $i++) {
    foreach ($arrData as $item) {
        mb_convert_variables('GBK', 'UTF-8', $item);
        fputcsv($fp, $item);
    }
    //刷新输出缓冲到浏览器
    ob_flush();
    flush();//必须同时使用 ob_flush() 和flush() 函数来刷新输出缓冲。
}
fclose($fp);
exit();
