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:
// 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:
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:
$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:
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:
// Set the title
$excel->setTitle('Product list');
// Set the creator
$excel->setCreator('Voja Janjic');
// Set description
$excel->setDescription('<a href="/tag/PHP/" target="_blank" class="keywords">PHP</a> 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');
