一、系统说明

“经历过方知深浅”,开发该系统目的主要是为了学习,理顺系统开发的流程,将理论与实践应用进一步的结合,这也是php学习入门进阶的一个重要里程碑。

开发环境:Apache2.0+php5.4+mysql5.5
开发工具:文本编辑器(dreamweaver/editplus)

二、系统开发要点

1.smarty的应用
2.后台会员、权限验证
3.对象、类的封装

三、系统模块分类

1.MySQL数据库
主要有5个数据表:全站配置表p_config、后台会员表p_admin、新闻分类表p_<a href="http://www.php.cn/wiki/165.html" target="_blank">new</a>s<a href="http://www.php.cn/wiki/164.html" target="_blank">class</a>、新闻标题表p_newsbase、新闻内容表p_newscontent,如下图所示:

数据表

2.程序文件
网站目录结构一览表,如图:

四、开发详解

下面将按照一定流程分项讲解细节(css等文件不详细列出):
1.mysql数据库的创建
下面依次贴上各个表的配置图:

  • p_config表

p_config表

  • p_admin表

微型新闻系统的开发

p_admin表

  • p_newsclass表

微型新闻系统的开发

p_newsclass表

  • p_newsbase表

微型新闻系统的开发

p_newsbase表

  • p_newscontent表

微型新闻系统的开发

p_newscontent表

详解:

  • p_newsclass,p_newsbase,p_newscontent这三个表存在关联关系:
    p_newsbase|cid --> p_newsclass|id
    p_newscontent|nid --> p_newsbase|id

  • p_newsclassf_id=0时为顶级栏目,f_id=1表示该分类属于id为1的分类的子分类。

2.smarty配置
将smarty文件放置根目录common文件夹下,下一步安装配置:
(1).设置config.php配置文件,源码如下:

<?php>

//数据库常用变量配置
$myhost       ="localhost";   //主机名
$mydbuser     ="root";        //数据库用户名
$mydbpw       ="password";    //数据库密码
$mydbname     ="news_system"; //数据库名称
$mydbcharset  ="GBK";         //数据库编码

//smarty常用变量配置
$smarty_template_dir   ='./templates/';     //模板路径变量
$smarty_compile_dir    ='./templates_c/';   //编译目录模板变量
$smarty_config_dir     ='./configs/';       //配置目录变量
$smarty_cache_dir      ='./cache/';         //缓存目录变量
$smarty_caching        ='false';            //缓存开关变量         
$smarty_delimiter      =explode("|","{|}"); //定界符变量,返回数组array([0]=>'{',[1]=>'}')

?>

(2).设置global全局调用文件,源码如下:

<?php
include_once(&#39;./configs/config.php&#39;);              //引入config.php
include_once(&#39;./common/smarty/Smarty.class.php&#39;);  //引入smarty.class.php
include_once(&#39;./common/mysql.class.php&#39;);          //引入mysql语句类文件
include_once(&#39;./common/action.class.php&#39;);         //引入动作执行类文件
include_once(&#39;./common/page.class.php&#39;);           //引入分页类文件

//实例化类,这里action已事先在继承了Mysql类
$db=new action($myhost,$mydbuser,$mydbpw,$mydbname,ALL_PS,$mydbcharset);

//配置smarty
$smarty = new smarty();
$smarty->template_dir    = $smarty_template_dir;   //模板目录
$smarty->compile_dir     = $smarty_compile_dir;    //编译目录
$smarty->config_dir      = $smarty_config_dir;     //配置目录
$smarty->cache_dir       = $smarty_cache_dir;      //缓存目录
$smarty->caching         = $smarty_caching;        //缓存开关
$smarty->left_delimiter  = $smarty_delimiter[0];   //左定界符
$smarty->right_delimiter = $smarty_delimiter[1];   //右定界符
$smarty->assign("t_dir",$smarty_template_dir);     //模板路径变量映射

?>

到现在,smarty已配置好。

3.mysql语句类
这里详细说明系统常用到的mysql自定义语句类:mysql.class.php,源码如下:

<?php
class mysql{
  private $db_host;
  private $db_user;
  private $db_pwd;
  private $db_database;
  private $coding;
  private $conn;
  private $sql;
  private $row;
  private $result;
  private $bulletin=true;    //是否开启错误记录
  private $show_error=true;  //测试阶段,显示所有错误,具有安全隐患,默认关闭

  //构造函数,初始化赋值,实例化后可直接传参
  public function construct($db_host,$db_user,$db_pwd,$db_database,$conn,$coding){
    $this->db_host=$db_host;
    $this->db_user=$db_user;
    $this->db_pwd=$db_pwd;
    $this->db_database=$db_database;
    $this->conn=$conn;
    $this->coding=$coding;
    $this->connect();
  }

  //连接数据库
  public function connect(){
    if ($this->conn == "pconn") {
      //永久链接
      $this->conn = mysql_pconnect($this->db_host, $this->db_user, $this->db_pwd);
    } else {
      //即时链接
      $this->conn = mysql_connect($this->db_host, $this->db_user, $this->db_pwd);
    }

    if (!mysql_select_db($this->db_database, $this->conn)) {
      if ($this->show_error) {
        $this->show_error("数据库不可用:", $this->db_database);
      }
    }
    mysql_query("set names $this->coding");
  }

  //数据库执行
  public function query($sql){
    if($sql=""){
      $this->show_error("SQL语句错误:","SQL查询语句为空");
    }
    $this->sql=$sql;
    $result=mysql_query($this->sql,$this->conn);

    if (!$result) {
      //调试中使用,sql语句出错时会自动打印出来
      if ($this->show_error) {
        $this->show_error("错误SQL语句:", $this->sql);
      }
    } else {
      $this->result = $result;
    }
  }

  //取得记录值,获取数组-索引和关联
  public function fetch_array(){
    return mysql_fetch_array($this->result);
  }

  //简化查询
  public function select($table,$columnName="*",$condition='',$debug=''){
    $condition=$condition ? "where" . $condition : NULL;
    if($debug){
      echo "select $columnName from $table $condition";
    }else{
      $this->query("select $columnName from $table $condition");
    }
  }

  //简化查询select
  public function findall($table){
    $this->query("select * from $table");
  }

  //取得上一步 INSERT 操作产生的 
  public function insert_id() {
    return mysql_insert_id();
  }

  //错误记录
  public function show_error($message="",$sql=""){
    if(!$sql){
      echo "<font color=&#39;red&#39;>" . $message . "</font>";
      echo "<br />";
    }else{
      echo "<fieldset>";
      echo "<legend>错误信息提示:</legend><br />";
      echo "<p style=&#39;font-size:14px; clear:both; font-family:Verdana, Arial, Helvetica, sans-serif;&#39;>";
      echo "<p style=&#39;height:20px; background:#000000; border:1px #000000 solid&#39;>";
      echo "<font color=&#39;white&#39;>错误号:12142</font>";
      echo "</p><br />";
      echo "错误原因:" . mysql_error() . "<br /><br />";
      echo "<p style=&#39;height:20px; background:#FF0000; border:1px #FF0000 solid&#39;>";
      echo "<font color=&#39;white&#39;>" . $message . "</font>";
      echo "</p>";
      echo "<font color=&#39;red&#39;><pre class="brush:php;toolbar:false">" . $sql . "
";           $ip=$this->getip();           if ($this->bulletin) {         $time = date("Y-m-d H:i:s");         $message = $message . "\r\n$this->sql" . "\r\n客户IP:$ip" . "\r\n时间 :$time" . "\r\n\r\n";         $server_date = date("Y-m-d");         $filename = $server_date . ".txt";         $file_path = "error/" . $filename;         $error_content = $message;         //$error_content="错误的数据库,不可以链接";         $file = "error"; //设置文件保存目录         //建立文件夹         if (!file_exists($file)) {           if (!mkdir($file, 0777)) {             //默认的 mode 是 0777,意味着最大可能的访问权             die("upload files directory does not exist and creation failed");            }         }             //建立txt日期文件         if (!file_exists($file_path)) {           //建立 “建立日期文件”           fopen($file_path,"w+");           //首先要确定文件存在并且可写           if (is_writable($file_path)) {             //使用添加模式打开$filename,文件指针将会在文件的开头             if(!$handle=fopen($file_path,'a')){               echo "不能打开文件 $filename";               exit;             }             //将$somecontent写入到我们打开的文件中。             if(!fwrite($handle,$error_content)){               echo "不能写入到文件 $filename";               exit;             }             echo "——错误记录被保存!";             //关闭文件             fclose($handle);           }else{             echo "文件 $filename 不可写";           }         }else{           //首先要确定文件存在并且可写           if (is_writable($file_path)) {             //使用添加模式打开$filename,文件指针将会在文件的开头             if (!$handle = fopen($file_path, 'a')) {               echo "不能打开文件 $filename";               exit;             }             //将$somecontent写入到我们打开的文件中。             if (!fwrite($handle, $error_content)) {               echo "不能写入到文件 $filename";               exit;             }             //echo "文件 $filename 写入成功";             echo "——错误记录被保存!";             //关闭文件             fclose($handle);           }else{             echo "文件 $filename 不可写";           }         }       }       echo "

";     echo "";     echo "
";   }     /*获得客户端真实的IP地址*/     function getip() {           if (getenv("HTTP_CLIENT_IP") && strcasecmp(getenv("HTTP_CLIENT_IP"), "unknown")) {             $ip = getenv("HTTP_CLIENT_IP");           } else           if (getenv("HTTP_X_FORWARDED_FOR") && strcasecmp(getenv("HTTP_X_FORWARDED_FOR"), "unknown")) {                 $ip = getenv("HTTP_X_FORWARDED_FOR");             } else                 if (getenv("REMOTE_ADDR") && strcasecmp(getenv("REMOTE_ADDR"), "unknown")) {                     $ip = getenv("REMOTE_ADDR");                 } else                     if (isset ($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], "unknown")) {                         $ip = $_SERVER['REMOTE_ADDR'];                     } else {                         $ip = "unknown";                     }         return ($ip);         }       } ?>

4.后台登录以及用户权限判断
后台登录以及用户权限的判断,主要通过session加密来实现,封装好权限判断函数,在每个后台页面引用即可。
(1).首先,我们需要先创建后台调用文件admin_global.php,源码如下:

<?php
session_start();
include_once ("../common/mysql.class.php"); //mysql类
include_once ("../configs/config.php"); //配置参数
include_once ("common/action.class.php"); //数据库操作类
include_once ("common/page.class.php"); //数据库操作

$db = new action($mydbhost, $mydbuser, $mydbpw, $mydbname, ALL_PS, $mydbcharset); //数据库操作类

//将存在的session[uid]和session[shell]赋值,便于后续的调用判断
$uid = $_SESSION[uid];
$shell = $_SESSION[shell];    
?>

(2).创建action.class.php文件,包含用户登录、权限判断等功能,源码如下:

<?php
class action extends mysql{

  //用户权限判断
  public function Get_user_shell($uid,$shell){
    $query=$this->select('p_admin',"*",'`uid`=\''.$uid.'\'');
    $us=is_array($row=$this->fetch_array($query));
    $ps=$us ? $shell=md5($row[username].$row[password]."TKBK") : FALSE;
    return $shell ? $row : NULL;
  }

  public function Get_user_shell_check($uid,$shell,$m_id=9){
    if($row=$this->Get_user_shell($uid,$shell)){
      if($row[m_id] <= $m_id){
        return $row;
      }else{
        echo "你无权限操作!";
        exit();
      }
    }else{
      $this->Get_admin_msg('index.php','请先登录');
    }
  }
    //===================================

  //用户登录时间超时
  public function Get_user_ontime($long='3600'){
    $new_time=mktime();
    $onlinetime=$_SESSION[ontime];
    if($new_time-$onlinetime>$long){
      echo "登录超时";
      session_destroy();
      exit();
    }else{
      $_SESSION[ontime]=mktime();
    }
  }

  //用户退出登录
  public function Get_user_out(){
    session_destroy();
    $this->Get_admin_msg('index.php','退出成功');
  }

  //用户登录
  public function Get_user_login($username,$password){
    $username=str_replace(" ","",$username);   //过滤提交上来username中的空格
    $query=$this->select('p_admin','*','`username` = \''.$username.'\'');//调用查询方法,查询管理员表中的username
    $us=is_array($row=$db->fetch_array($query));
    $ps=$us ? md5($password)==$row[password] : FALSE;

    if($ps){
      $_SESSION[uid]=$row[uid];
      $_SESSION[shell]=md5($row[username].$row[password]."TKBK");
      $_SESSION[ontime]=mktime();
      $this->Get_admin_msg('main.php','登录成功!');
    }else{
      $this->Get_admin_msg('index.php','密码或用户错误!');
      session_destroy();
    }
  }

  /**
    * 后台通用信息提示
    */
    public function Get_admin_msg($url, $show = '操作已成功!') {
        $msg = '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
        <html xmlns="http://www.w3.org/1999/xhtml"><head>
                <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
                <link rel="stylesheet" href="css/common.css" type="text/css" />
                <meta http-equiv="refresh" content="2; URL=&#39; . $url . &#39;" />
                <title>管理区域</title>
                </head>
                <body>
                <p id="man_zone">
                  <table width="30%" border="1" align="center"  cellpadding="3" cellspacing="0" class="table" style="margin-top:100px;">
                    <tr>
                      <th align="center" style="background:#cef">信息提示</th>
                    </tr>
                    <tr>
                      <td><p>' . $show . '<br />
                      2秒后返回指定页面!<br />
                      如果浏览器无法跳转,<a href="&#39; . $url . &#39;">请点击此处</a>。</p></td>
                    </tr>
                  </table>
                </p>
                </body>
                </html>';
        echo $msg;
        exit ();
    }  

}
?>

(3).登录首页/admin/index.php,源码如下:

<?php
include_once(&#39;admin_global.php&#39;);
if(!empty($_POST[username]) && !empty($_POST[password])){
    $db->Get_user_login($_POST[username],$_POST[password]);    
}
?>

<html>
  <head>
    <meta http-equiv=&#39;Content-Type&#39; content=&#39;text/html; charset=gb2312&#39;>
    <meta name=&#39;Author&#39; content=&#39;Alan&#39;>
    <link rev=MADE href=&#39;mailto:haowubai@hotmail.com&#39;><title>后台管理</title>
    <link rel=&#39;stylesheet&#39; type=&#39;text/css&#39; href=&#39;images/private.css&#39;>
    <script> if(self!=top){ window.open(self.location,'_top'); } </script>
  </head>
  <body>
    <br><br><br>
    <form action="" method="post">
    <table border=0 cellspacing=1 align=center class=form>
    <tr>
        <th colspan="2">用户登录</th>
    </tr>
           <tr>
             <td align="right">登录用户:</td>
             <td><input type="text" name="username" value="" size="20" maxlength="40"/>  </td>
           </tr>
           <tr>
            <td align="right">登录密码:</td>
            <td><input type="password" name="password" value="" size="20" maxlength="40"/>  </td>
           </tr>
           <tr>
            <td colspan="2" align="center" height=&#39;30&#39;>
             <input type="submit" name="update" value=" 登录 "/>
           </td>  
          </tr>
         </table>
       </form>
     </body>
</html>

到此已实现用户的后台登录验证,用户权限的判断只需将以下代码粘贴到每个后台页面即可:

include_once('admin_global.php');
$r=$db->Get_user_shell_check($uid,$shell);

(4).后台管理页面:
后台全局调用页面admin_global.php
后台首页main.php
左侧导航页面admin_left.php
网站参数配置页面admin_main.php
新闻栏目分类管理页面admin_news_class.php
新闻列表页面admin_news_list.php
新闻编辑添加页面admin_news_add.php
各个页面源码如下:

admin_global.php:引入各类文件

<?php
session_start();
include_once ("../common/mysql.class.php"); //mysql类
include_once ("../configs/config.php"); //配置参数
include_once ("common/action.class.php"); //数据库操作类
include_once ("common/page.class.php"); //数据库操作

$db = new action($mydbhost, $mydbuser, $mydbpw, $mydbname, ALL_PS, $mydbcharset); //数据库操作类.

$uid = $_SESSION[uid];
$shell = $_SESSION[shell];    
?>

main.php:利用frame标签引入各个功能页面

<!DOCTYPE html>
<html>
  <head><title>网站后台控制面板</title>
    <meta http-equiv=Content-Type content="text/html; charset=gb2312">

(5)分页功能page.class.php
后台和前台分别调用了不同的分页函数,以免混淆,不过由于函数功能基本不一样,这里只贴出前台的分页函数源码:

<?php

$page=$_GET[&#39;page&#39;];
if(!function_exists(pageft)){

    function pageft($total,$displaypg){

        global $page,$pagenav,$firstcount;

        $GLOBALS["displaypg"]=$displaypg;

        if(!$page) $page=1;

        //获取url
        $url=$_SERVER[&#39;REQUEST_URI&#39;];
        $parse_url=parse_url($url);
        $url_query=ereg_replace("(^|&)page=$page","",$parse_url["query"]);
        $url=$parse_url[path]."?".$url_query."&page";

        $lastpg=ceil($total/$displaypg);
        $page=min($lastpg,$page);
        $prepg=$page-1;
        $nextpg=$page+1;

        //数据记录提取初始值
        $firstcount=($page-1)*$displaypg;

        $pagenav=&#39;&#39;;
        $pagenav.=&#39;共&#39;.$total.&#39;条记录 &#39;;

        if($page==1){
            $pagenav.=" <span>首页</span> ";
        }else{
            $pagenav.="<a href=&#39;$url=1&#39;>首页</a> ";
        }

        if($page==1){
            $pagenav.=" <span>上一页</span> ";
        }else{
            $pagenav.="<a href=&#39;$url=$prepg&#39;>上一页</a> ";
        }

        for($i=1;$i<=$lastpg;$i++){
            if($i==$page) $pagenav.=" <span>$i</span> ";
            else $pagenav.=" <a href=&#39;$url=$i&#39;>$i</a> ";    
        }

        if($page==$lastpage){
            $pagenav.=" <span>下一页</span> ";
        }else{
            $pagenav.="<a href=&#39;$url=$nextpg&#39;>下一页</a> ";
        }

        if($page==$lastpg){
            $pagenav.=" <span>末页</span> ";
        }else{
            $pagenav.="<a href=&#39;$url=$lastpg&#39;>末页</a> ";
        }

    }
}
?>

(6)前台首页
包括首页程序文件index.php,smarty模板文件index.html,源码如下:
index.php:

<?php

include_once(&#39;global.php&#39;);

$sql="select * from `p_newsclass` where f_id=0 order by id DESC";
$query=$db->query($sql);

    $sm_class[]=array('name'=>$row_class[name],'id'=>$row_class[id]);    
}

$smarty->assign("sm_class",$sm_class);

$sql="select * from `p_newsbase` order by id DESC limit 5";
$query=$db->query($sql);
while($row_news=$db->fetch_array($query)){
    $sm_news[]=array('title'=>$row_news[title],'id'=>$row_news[id]);
}

$smarty->assign('sm_news',$sm_news);

$sql="select * from `p_config`";
$query=$db->query($sql);
while($row_config=$db->fetch_array($query)){
    $sm_config[$row_config[name]]=$row_config[values];    
}



$smarty->assign('sm_config',$sm_config);
$smarty->display("index.html");
