使用PHP开发的库存盘点模块在企业资源计划（ERP）系统中的应用

CREATE TABLE `inventory` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `material_number` varchar(50) NOT NULL COMMENT '物料编号',
  `material_name` varchar(100) NOT NULL COMMENT '物料名称',
  `quantity` decimal(10,2) NOT NULL COMMENT '库存数量',
  `unit` varchar(10) NOT NULL COMMENT '单位',
  `last_inventory_time` datetime NOT NULL COMMENT '最后盘点时间',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

<?php
// 连接数据库
$conn = new mysqli("localhost", "username", "password", "database");

// 查询库存信息
$sql = "SELECT * FROM inventory";
$result = $conn->query($sql);

// 输出库存信息表
echo "<table>";
echo "<tr><th>物料编号</th><th>物料名称</th><th>库存数量</th><th>单位</th><th>最后盘点时间</th></tr>";

while ($row = $result->fetch_assoc()) {
    echo "<tr>";
