如何利用PHP和Vue开发仓库管理的出库管理功能

<?php

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

// 检查连接是否成功
if ($conn->connect_error) {
  die("数据库连接失败: " . $conn->connect_error);
}

// 获取出库单列表
function getStockOutList() {
  global $conn;
  $sql = "SELECT * FROM stock_out";
  $result = $conn->query($sql);
  
  if ($result->num_rows > 0) {
    $output = array();
    while($row = $result->fetch_assoc()) {
      $output[] = $row;
    }
    return $output;
  } else {
    return array();
  }
}

// 创建出库单
function createStockOut($out_date, $operator) {
  global $conn;
  $sql = "INSERT INTO stock_out (out_date, operator) VALUES ('$out_date', '$operator')";
  
  if ($conn->query($sql) === TRUE) {
    return true;
  } else {
    return false;
  }
}

// 删除出库单
function deleteStockOut($id) {
  global $conn;
  $sql = "DELETE FROM stock_out WHERE id = '$id'";
  
  if ($conn->query($sql) === TRUE) {
    return true;
  } else {
    return false;
  }
}

// 获取出库物品列表

  global $conn;
  $sql = "SELECT * FROM stock_out_items WHERE out_id = '$out_id'";
  $result = $conn->query($sql);
  
  if ($result->num_rows > 0) {
    $output = array();
    while($row = $result->fetch_assoc()) {
      $output[] = $row;
    }
    return $output;
  } else {
    return array();
  }
}

// 创建出库物品
