app.php入口文件執(zhí)行的方法開(kāi)始跑框架流程

<?php
class coreapp {
  static function run() {
    $a = $_SERVER[&#39;REQUEST_URI&#39;];
    $uri = rtrim(preg_replace(&#39;/\?.*/&#39;, &#39;&#39;, $_SERVER[&#39;REQUEST_URI&#39;]), &#39;/&#39;);
    $params = explode(&#39;/&#39;, trim($uri, &#39;/&#39;));
    $count = count($params);
    if ($count >?1)?{
??????$controller?=?$params[0];
??????$method?=?$params[1];

??????$controller?=?'index';

}

根據(jù)請(qǐng)求uri去找對(duì)應(yīng)的controller, 用call_user_func_array()的方式調(diào)用controller里的方法

根目錄/controller/test.php

<?php
class?controllertest?{
??public?function?write($controller,?$method)?{
????//configtest::load('test');
????modeltest::write($controller,?$method);
??}
}

這里其實(shí)調(diào)用不一定要調(diào)用model里的test方法，可以調(diào)model目錄下的任意文件，在此之前可以去都讀一些config文件等等操作。

根目錄/model/test.php

<?php
class?modeltest?{
??public?function?write($model,?$method)?{
????echo?'From?controller:'.$model.'?to?model:?'?.?$model?.?'?,method:?'?.?$method;
??}
}

例如hostname/test/write 這個(gè)請(qǐng)求就會(huì)從入口文件進(jìn)來(lái)，經(jīng)過(guò)coreapp::run就會(huì)找到controller下對(duì)應(yīng)的的controllertest類，執(zhí)行write()
