要使用純PHP創建或編輯Excel電子表格，我們將使用PHPExcel庫，它可以讀寫許多電子表格格式，包括xls，xlsx，ods和csv。在我們繼續之前，仔細檢查您的服務器上是否有PHP 5.2或更高版本以及安裝了以下PHP擴展：php_zip，php_xml和php_gd2。
創建電子表格
創建電子表格是PHP應用程序中最常見的用例之一，用于將數據導出到Excel電子表格。查看以下代碼，了解如何使用PHPExcel創建示例Excel電子表格：
// Include PHPExcel library and create its objectrequire('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');如果要下載電子表格而不是將其保存到服務器，請執行以下操作：
header('Content-Type: application/vnd.ms-excel');header('Content-Disposition: attachment;filename="file.xlsx"');header('Cache-Control: max-age=0');$writer->save('php://output');編輯現有電子表格
在PHP中編輯電子表格與創建電子表格類似：
// Include PHPExcel library and create its objectrequire('PHPExcel.php');// Load an existing spreadsheet$phpExcel = PHPExcel_IOFactory::load('products.xlsx');// Get the first sheet$sheet = $phpExcel ->getActiveSheet();// Remove 2 rows starting from the row 2$sheet ->removeRow(2,2);// Insert one new row before row 2$sheet->insertNewRowBefore(2, 1);// Create the PHPExcel spreadsheet writer object// We will create xlsx file (Excel 2007 and above)$writer = PHPExcel_IOFactory::createWriter($phpExcel, "Excel2007");// Save the spreadsheet$writer->save('products.xlsx');準備電子表格進行打印
要準備電子表格進行打印，我們將設置紙張方向，尺寸和邊距：
$sheet->getPageSetup()->setOrientation(PHPExcel_Worksheet_PageSetup::ORIENTATION_LANDSCAPE);$sheet -> getPageSetup()->setPaperSize(PHPExcel_Worksheet_PageSetup::PAPERSIZE_A4); $sheet->getPageMargins()->setTop(1);$sheet ->getPageMargins()->setRight(0.75);$sheet ->getPageMargins()->setLeft(0.75);$sheet ->getPageMargins()->setBottom(1);
將PHPExcel與Laravel一起使用
PHPExcel庫也可以在Laravel框架中使用。查看以下PHP包（此處）并通過Composer安裝它。完成安裝步驟后，您可以使用以下代碼將數據從數據庫導出到Excel電子表格中：
Excel::create('Products', function($excel) { // Set the title $excel->setTitle('Product list'); // Set the creator $excel->setCreator('Voja Janjic'); // Set description $excel->setDescription('PHP Excel spreadsheet testing'); $excel->sheet('Products', function($sheet) { // Get data from the database $products = Product::all(); // Generate header row $sheet->row(1, array( 'ID', 'Product', 'Price', 'Quantity', )); // Generate data rows $i = 2; foreach($products as $product) { $sheet->row($i, array( $product->product_id, $product->product_name, $product->price, $variety->quantity, )); $i++; } });})->export('xlsx');新聞熱點
