在PHP中建立和編輯Excel電子表格
阿新 • • 發佈:2018-12-09
要使用純PHP建立或編輯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,仔細檢查您的伺服器上是否有PHP 5.2或更高版本以及安裝了以下PHP擴充套件:php_zip,php_xml和php_gd2。
建立電子表格
建立電子表格是PHP應用程式中最常見的用例之一,用於將資料匯出到Excel電子表格。檢視以下程式碼,瞭解如何使用PHPExcel建立示例Excel電子表格:
// 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 // 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儲存到伺服器,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中編輯電子表格與建立電子表格類似:
// 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');
準備電子表格進行列印
要準備電子表格進行列印,我們將設定紙張方向,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); $sheet ->getPageMargins()->setBottom(1);
將PHPExcel與Laravel一起使用
PHPExcel庫也可以在Laravel框架中使用。檢視以下PHP包(此處)並通過Composer安裝它。完成安裝步驟後,您可以使用以下程式碼將資料從資料庫匯出到Excel電子表格中:
Excel::create('Products', function($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');

PHPExcel提供了許多本教程中未提及的功能,例如函式,計算和圖表。
