PHP简单MVC架构
http://blog.csdn.net/haiqiao_2010/article/details/12166283
由于需要搭建一个简单的框架来进行API接口开发,所以简单的mvc框架当然是首选.最原始,最简洁的mvc框架.下面来介绍下.
一. 项目目录结构:
app
|-controller 存放控制器文件
|-model 存放模型文件
|-view 存放视图文件
core
|-lib 存放自定义类库
|-config 存放配置文件
|--config.php 系统配置文件
|--conn.php 数据库连接文件
|--db_config.php
数据库配置文件
|-mysql_db.php 数据库类文件
|-runtime 缓存文件
db_caches 数据库缓存文件
logs日志文件
|-index.php 入口文件
| -dispatcher.php
|
-loader.php
|
-router.php
二.项目架构
1.先介绍index.php,附源码:
- <?php
- include("./core/ini.php");
- include("./core/config/config.php");
- include("./core/global.fun.php");
- include("./core/common.php");
- initializer::initialize();//加载将要用到的目录文件<span style="font-family:verdana,sans-serif; font-size:13px; line-height:19px">,即调用initializer类的一个静态函数initialize,因为我们在ini.php,设置了include_path,以及定义了__autoload,所以程序会自动在core/main目录查找initializer.php.</span>
- $router = loader::load("router");//加载URL处理文件,对url进行解析--<span style="font-family:verdana,sans-serif; font-size:13px; line-height:19px">加载loader函数的静态函数load</span>
- dispatcher::dispatch($router);//<span style="font-family:verdana,sans-serif; font-size:13px; line-height:19px">router.php文件,这个文件的作用就是映射URL,对URL进行解析.</span>根据解析到的URL参数加载相关controller及action
- ?>
2.初始化项目文件
./core/ini.php 源码:
- <?php
- set_include_path(get_include_path() . PATH_SEPARATOR . "core/main");
- //set_include_path — Sets the include_path configuration option
- function __autoload($object){
- require_once("{$object}.php");
- }
这个文件首先设置了include_path,也就是我们如果要找包含的文件,告诉系统在这个目录下查找。其实我们定义__autoload()方法,这个方法是在PHP5增加的,就是当我们实例化一个函数的时候,如果本文件没有,就会自动去加载文件
3.加载系统配置文件./core/config.php
源码:
- <?php
- /*
- * 设置页面编码格式
- */
- header("content-type:text/html;charset=utf-8");
- //禁用错误报告
- error_reporting(0);
- date_default_timezone_set("PRC");
- //定义常量
- define("URL_PATH","<a target="_blank" href="http://blog.csdn.net/haiqiao_2010">http://blog.csdn.net/haiqiao_2010</a>");//服务器IP
- define('IMG_PATH',"<a target="_blank" href="http://blog.csdn.net/haiqiao_2010">http://blog.csdn.net/haiqiao_2010</a>");//服务器图片目录
- //判断日志是否开启
- defined("APP_LOG") or define("APP_LOG",true);
- if (APP_LOG) {
- $GLOBALS['log'] = new APIlog();
- set_exception_handler(array($GLOBALS['log'],'quit'));
- set_error_handler(array($GLOBALS['log'],'error_handle'));
- }
- define('IS_CGI',substr(PHP_SAPI, 0,3)=='cgi' ? 1 : 0 );
- define('IS_WIN',strstr(PHP_OS, 'WIN') ? 1 : 0 );
- define('IS_CLI',PHP_SAPI=='cli'? 1 : 0);
- if(!defined('APP_NAME')) define('APP_NAME', basename(dirname($_SERVER['SCRIPT_FILENAME'])));
- if(!IS_CLI) {
- // 当前文件名
- if(!defined('_PHP_FILE_')) {
- if(IS_CGI) {
- //CGI/FASTCGI模式下
- $_temp = explode('.php',$_SERVER["PHP_SELF"]);
- define('_PHP_FILE_', rtrim(str_replace($_SERVER["HTTP_HOST"],'',$_temp[0].'.php'),'/'));
- }else {
- define('_PHP_FILE_', rtrim($_SERVER["SCRIPT_NAME"],'/'));
- }
- }
- if(!defined('__ROOT__')) {
- // 网站URL根目录
- if( strtoupper(APP_NAME) == strtoupper(basename(dirname(_PHP_FILE_))) ) {
- $_root = dirname(dirname(_PHP_FILE_));
- }else {
- $_root = dirname(_PHP_FILE_);
- }
- define('__ROOT__', (($_root=='/' || $_root=='\\')?'':$_root));
- }
- //支持的URL模式
- define('URL_COMMON', 0); //普通模式
- define('URL_PATHINFO', 1); //PATHINFO模式
- define('URL_REWRITE', 2); //REWRITE模式
- define('URL_COMPAT', 3); // 兼容模式
- }
- if(!defined('APP_ROOT')) {//项目根路径
- // 网站URL根目录
- $_root = dirname(_PHP_FILE_);
- $_root = (($_root=='/' || $_root=='\\')?'':$_root);
- $_root = str_replace("/system","",$_root);
- define('APP_ROOT', $_root );
- }
- if(!defined('APP_ROOT_PATH'))//项目绝对路径
- define('APP_ROOT_PATH', str_replace("\\","/",substr(dirname(__FILE__),0,-11)));
- if(!defined('PAGE_SIZE'))//im:页面大小
- define('PAGE_SIZE',15);
- ?>
4.加载通用的方法的文件./core/global_fun.php
源码:
- <?php
- //header("content-type:text/html;charset=utf-8");
- /*

6.加载./initializer.php,initializer()用于将所有公用的文件目录在此函数里声明
这就话就是调用initializer类的一个静态函数initialize,因为我们在ini.php,设置了include_path,以及定义了__autoload,所以程序会自动在core/main目录查找initializer.php.
- <?php
- class initializer
- {
- public static function initialize() {
- set_include_path(get_include_path().PATH_SEPARATOR . "core/main");
- set_include_path(get_include_path().PATH_SEPARATOR . "core/main/cache");
- set_include_path(get_include_path().PATH_SEPARATOR . "core/helpers");
- set_include_path(get_include_path().PATH_SEPARATOR . "core/libraries");
- set_include_path(get_include_path().PATH_SEPARATOR . "core/config");
- set_include_path(get_include_path().PATH_SEPARATOR . "app/controllers");
- set_include_path(get_include_path().PATH_SEPARATOR."app/models");
- set_include_path(get_include_path().PATH_SEPARATOR."app/views");
- }
- }
- ?>
7.加载./loader.php文件,源码:
- <?php
- class loader
- {
- private static $loaded = array();
- public static function load($object){
- $valid = array(
- "library",
- "view",
- "model",
- "helper",
- "router",
- "config",
- "hook",
- "cache",
- "db");
- if (!in_array($object,$valid)){
- // throw new Exception("Not a valid object '{$object}' to load");
- ajax_return(array('recode'=>"0003",'msg'=>"非法操作","data"=>"Not a valid object '{$object}' to load"));
- }
- if (empty(self::$loaded[$object])){
- self::$loaded[$object]= new $object();
- }
- return self::$loaded[$object];
- }
- }
- ?>
8.加载控制层文件./router.php,源码:
- <?php
- class router
- {
- private $route;
- private $controller;
- private $action;
- private $params;
- public function __construct()
- {
- //base64_decode(str)解码
- $routeParts=$_GET;
- // $routeParts=base64_decode($_GET);
- if (!isset($routeParts['c'])){
- ajax_return(array('recode'=>"0003",'msg'=>"非法操作",'data'=>"Controller is null"));
- }
- $this->route = $routeParts['c'];
- $this->controller=$routeParts['c'];
- $this->action=isset($routeParts['act'])? $routeParts['act']:"index";
- array_shift($routeParts);
- array_shift($routeParts);
- $this->params=$routeParts;
- }
- public function getAction() {
- if (empty($this->action)) $this->action="index";
- return $this->action;
- }
- public function getController() {
- return $this->controller;
- }
- public function getParams() {
- return $this->params;
- }
- }
- ?>
9.加载数据库连接文件./core/conn.php,源码:
- <?php
- /*
- * 数据库连接
- */
- //第一种方法:直接写入数据库连接参数
- // $dblink=mysql_connect("127.0.0.1:3306","sara","abc123");
- // mysql_select_db("ipolarbear",$dblink);
- // mysql_query("SET NAMES UTF8");
- // if (!$dblink) {
- // mysql_query("SET NAMES UTF8");
- // die (json_encode(array('recode'=>"0009",'msg'=>"连接数据库失败" . mysql_error (),'data'=>'')));
- // }
- //第二种方法:定义DB类,加载数据库配置,对数据库SQL进行封装
- //加载数据库配置
- $dbcfg = require APP_ROOT_PATH."core/config/db_config.php";
- if(!defined('DB_PREFIX'))//im:数据库表前缀
- define('DB_PREFIX', $dbcfg['DB_PREFIX']);
- if(!file_exists(APP_ROOT_PATH.'core/runtime/db_caches/'))
- mkdir(APP_ROOT_PATH.'core/runtime/db_caches/',0777);
- $pconnect = false;
- $GLOBALS['db'] = new mysql_db($dbcfg['DB_HOST'].":".$dbcfg['DB_PORT'], $dbcfg['DB_USER'],$dbcfg['DB_PWD'],$dbcfg['DB_NAME'],'utf8',$pconnect);
- mysql_query("SET NAMES UTF8");//相当于character_set_client(),character_set_connection(),character_set_results()客户端 连接器 返回值三者同时设置编码方式
- //检查PHP是否连接上MYSQL
- if(mysqli_connect_errno()){
- die (json_encode(array('recode'=>"0009",'msg'=>"连接数据库失败:" . mysql_error (),'data'=>'')));
- }
- //end 定义DB
- ?>
10.加载数据库配置文件./core/db_config.php,源码:
- <?php
- return array(
- 'DB_HOST'=>'localhost',
- 'DB_NAME'=>'ip',
- 'DB_USER'=>'sara',
- 'DB_PWD'=>'abc123',
- 'DB_PORT'=>'3306',

- );
- ?>
11.加载数据库类文件./core/mysql_db.php,源码:
