Code generation for the inventory information export function in the PHP inventory management system

In the inventory management system, exporting inventory information is a common requirement, which allows users to easily export inventory data as Excel, CSV and other formats for data analysis, report generation and other operations. This article will introduce how to use PHP to write the inventory information export function of the inventory management system and provide relevant code examples.

First of all, before writing code, we need to ensure that the PHPExcel library has been installed on the server. It is a powerful PHP library that can help us process Excel files easily. The library can be installed through the following command:

composer require phpoffice/phpexcel

After the installation is completed, we can start writing the code for the inventory information export function.

<?php
require_once 'vendor/autoload.php';
use PhpOfficePhpSpreadsheetSpreadsheet;
use PhpOfficePhpSpreadsheetWriterXlsx;

// 创建Excel对象
$spreadsheet = new Spreadsheet();

// 选择活动的工作表
$sheet = $spreadsheet->getActiveSheet();

// 设置表头
$sheet->setCellValue('A1', '商品名称');
$sheet->setCellValue('B1', '库存数量');

// 模拟获取库存数据
$inventoryData = [
    ['商品A', 100],
    ['商品B', 200],
    ['商品C', 150],
];

// 写入库存信息
$row = 2;
foreach ($inventoryData as $item) {
    $sheet->setCellValue('A' . $row, $item[0]);
    $sheet->setCellValue('B' . $row, $item[1]);
    $row++;
}

// 设置文件名和格式
$filename = 'inventory_' . date('YmdHis') . '.xlsx';

// 创建导出对象
$writer = new Xlsx($spreadsheet);

// 将Excel文件保存到服务器
$writer->save($filename);

// 设置响应头，提示下载
header("Content-Disposition: attachment; filename="$filename"");
header("Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
header("Content-Length: " . filesize($filename));
header("Cache-Control: max-age=10");
readfile($filename);

// 删除服务器上的Excel文件
unlink($filename);

The above code creates an Excel object through the PHPExcel library and sets the header. Next, we simulated obtaining the inventory data and using a loop to write the data into Excel. Then, we set the exported file name and created the export object. Finally, by setting the response header, the Excel file is returned to the user and prompted to download.

It should be noted that in actual use, we need to obtain inventory data according to our own business logic and integrate the code into the inventory management system. In addition, you can also customize the Excel style according to specific needs, such as setting cell formats, merging cells, etc.

To sum up, this article introduces how to use PHP to write the inventory information export function of the inventory management system, and provides corresponding code examples. Through this function, users can easily export inventory data to Excel files to facilitate data analysis and report generation. Hope this article helps you!
