雙專業畢業論文做了一個小型企業庫存管理系統，使用PHP&mysql組合進行開發。頭一次開發稍微大一點的東西，php也是自學的。這里想跟大家一起分享一下

check_login 模塊

復制代碼代碼如下:

<?php
session_start();
$workid=$_GET['wid'];//獲取工作號
if($workid!=$_SESSION['$workid']||$workid==''){
echo "<script language=javascript>alert('您還沒有登陸，無法管理!');location.href='login.php';</script>";
}
?>

function.inc//主要包括數據庫連接模塊

復制代碼代碼如下:

<?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());
}
//改變客戶端字符集編碼為gb2312
mysql_query("SET NAMES gb2312");
return $id;
}
?>

倉庫管理界面storage.php

復制代碼代碼如下:

2 <?php
3 include "inc/check_login.php";
4 include "inc/function.inc";
5 $id=mysql_link("storage","storage");//建立storage連接
6
7 $query="select * from admin where admin_id='$workid'";//定位倉庫
8 $result=mysql_query($query,$id);
9 $info=mysql_fetch_array($result,MYSQL_ASSOC);
$stoid=$info['storage_id'];
?>
