PHP中创建和编辑Excel表格的方法

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：

$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：

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：

// 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：

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：

// Set the title $excel->setTitle('Product list'); // Set the creator $excel->setCreator('Voja Janjic'); // Set description $excel->setDescription('<a href="https://www.jb51.cc/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');
