要使用纯PHP创建或编辑Excel电子表格，我们将使用PHPExcel库，它可以读写许多电子表格格式，包括xls，xlsx，ods和csv。在我们继续之前，仔细检查您的服务器上是否有PHP 5.2或更高版本以及安装了以下PHP扩展：php_zip，php_xml和php_gd2。

创建电子表格

创建电子表格是PHP应用程序中最常见的用例之一，用于将数据导出到Excel电子表格。查看以下代码，了解如何使用PHPExcel创建示例Excel电子表格： (推荐学习：PHP视频教程)

// Include PHPExcel library and create its object

require('PHPExcel.php');

$phpExcel = new PHPExcel;

// Set default font to Arial

$phpExcel->getDefaultStyle()->getFont()->setName('Arial');

// Set default font size to 12

$phpExcel->getDefaultStyle()->getFont()->setSize(12);

// Set spreadsheet properties – title, creator and description

$phpExcel ->getProperties()->setTitle("Product list");

$phpExcel ->getProperties()->setCreator("Voja Janjic");

$phpExcel ->getProperties()->setDescription("PHP Excel spreadsheet testing.");

// Create the PHPExcel spreadsheet writer object

// We will create xlsx file (Excel 2007 and above)

$writer = PHPExcel_IOFactory::createWriter($phpExcel, "Excel2007");

// When creating the writer object, the first sheet is also created

// We will get the already created sheet

$sheet = $phpExcel ->getActiveSheet();

// Set sheet title

$sheet->setTitle('My product list');

// Create spreadsheet header

$sheet ->getCell('A1')->setValue('Product');

$sheet ->getCell('B1')->setValue('Quanity');

$sheet ->getCell('C1')->setValue('Price');

// Make the header text bold and larger

$sheet->getStyle('A1:D1')->getFont()->setBold(true)->setSize(14);

// Insert product data

// Autosize the columns

$sheet->getColumnDimension('A')->setAutoSize(true);

$sheet->getColumnDimension('B')->setAutoSize(true);

$sheet->getColumnDimension('C')->setAutoSize(true);

// Save the spreadsheet

$writer->save('products.xlsx');

如果要下载电子表格而不是将其保存到服务器，请执行以下操作：

header('Content-Type: application/vnd.ms-excel');

header('Content-Disposition: attachment;filename="file.xlsx"');

header('Cache-Control: max-age=0');

$writer->save('php://output');
