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：
代码语言：javascript复制// 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：
代码语言：javascript复制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：
代码语言：javascript复制// 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
$writer- save('products.xlsx');准备电子表格进行打印
要准备电子表格进行打印，我们将设置纸张方向，尺寸和边距：
代码语言：javascript复制$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);
$sheet - getPageMargins()- setBottom(1);将PHPExcel与Laravel一起使用
PHPExcel库也可以在Laravel框架中使用。查看以下PHP包（此处）并通过Composer安装它。完成安装步骤后，您可以使用以下代码将数据从数据库导出到Excel电子表格中：
代码语言：javascript复制Excel::create('Products', function($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');
