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
initializer::initialize();
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.
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.
定义了一个静态函数,initialize函数,这个函数就是设置include_path,这样,以后如果包含文件,或者__autoload,就会去这些目录下查找。
- <?php
- class initializer

7.加载./loader.php文件,源码:

8.加载控制层文件./router.php,源码:

9.加载数据库连接文件./core/conn.php,源码:
