双专业毕业论文做了一个小型企业库存管理系统，使用PHP&mysql组合进行开发。头一次开发稍微大一点的东西，php也是自学的。这里想跟大家一起分享一下

check_login 模块

 
<!--用户登陆检验模块--> 
<?php 
session_start(); 
$workid=$_GET['wid'];//获取工作号 
if($workid!=$_SESSION['$workid']||$workid==''){ 
echo "<script language=javascript>alert('您还没有登陆，无法管理!');location.href='login.php';</script>"; 
} 
?> 

function.inc//主要包括数据库连接模块

复制代码代码如下:

 
<?php 
function mysql_link($user="admin",$password="admin",$database="systembase"){ 
$id=mysql_connect("localhost",$user,$password); 
if(!$id){ 
die('Could not connect: ' . mysql_error()); 
} 
if (!mysql_select_db($database,$id)){ 
die ("Can\'t select_db : " . mysql_error()); 
} 
//改变客户端字符集编码为gb2312 
mysql_query("SET NAMES gb2312"); 
return $id; 
} 
?> 

仓库管理界面storage.php

复制代码代码如下:

 
<!--仓库管理员管理界面--> 
2 <?php 
3 include "inc/check_login.php"; 
4 include "inc/function.inc"; 
5 $id=mysql_link("storage","storage");//建立storage连接 
6 
7 $query="select * from admin where admin_id='$workid'";//定位仓库 
8 $result=mysql_query($query,$id); 
9 $info=mysql_fetch_array($result,MYSQL_ASSOC); 
$stoid=$info['storage_id']; 
?>
