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:
- // 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
- //phpfensi.com
- // 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');
编辑现有电子表格:
在PHP中编辑电子表格与创建电子表格类似:
- // Include PHPExcel library and create its object
- require('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');
准备电子表格进行打印
要准备电子表格进行打印,我们将设置纸张方向,尺寸和边距:
- $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);
- $sheet ->getPageMargins()->setBottom(1);
将PHPExcel与Laravel一起使用:
PHPExcel库也可以在Laravel框架中使用。查看以下PHP包(此处)并通过Composer安装它。完成安装步骤后,您可以使用以下代码将数据从数据库导出到Excel电子表格中:
- Excel::create('Products', function($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');
